When she was a child, Mary Ellen Wiltrout PhD ’09 didn’t want to follow in her mother’s footsteps as a K-12 teacher. Growing up in southwestern Pennsylvania, Wiltrout was studious with an early interest in science — and ended up pursuing biology as a career.

But following her doctorate at MIT, she pivoted toward education after all. Now, as the director of blended and online initiatives and a lecturer with the Department of Biology, she’s shaping biology pedagogy at MIT and beyond.

Establishing MOOCs at MIT

To this day, E.C. Whitehead Professor of Biology and Howard Hughes Medical Institute (HHMI) investigator emeritus Tania Baker considers creating a permanent role for Wiltrout one of the most consequential decisions she made as department head.

Since launching the very first MITxBio massive online open course 7.00x (Introduction to Biology – the Secret of Life) with professor of biology Eric Lander in 2013, Wiltrout’s team has worked with MIT Open Learning and biology faculty to build an award-winning repertoire of MITxBio courses.

MITxBio is part of the online learning platform edX, established by MIT and Harvard University in 2012, which today connects 86 million people worldwide to online learning opportunities. Within MITxBio, Wiltrout leads a team of instructional staff and students to develop online learning experiences for MIT students and the public while researching effective methods for learner engagement and course design.

“Mary Ellen’s approach has an element of experimentation that embodies a very MIT ethos: applying rigorous science to creatively address challenges with far-reaching impact,” says Darcy Gordon, instructor of blended and online initiatives.

Mentee to motivator

Wiltrout was inspired to pursue both teaching and research by the late geneticist Elizabeth “Beth” Jones at Carnegie Mellon University, where Wiltrout earned a degree in biological sciences and served as a teaching assistant in lab courses.

“I thought it was a lot of fun to work with students, especially at the higher level of education, and especially with a focus on biology,” Wiltrout recalls, noting she developed her love of teaching in those early experiences.

Though her research advisor at the time discouraged her from teaching, Jones assured Wiltrout that it was possible to pursue both.

Jones, who received her postdoctoral training with late Professor Emeritus Boris Magasanik at MIT, encouraged Wiltrout to apply to the Institute and join American Cancer Society and HHMI Professor Graham Walker’s lab. In 2009, Wiltrout earned a PhD in biology for thesis work in the Walker lab, where she continued to learn from enthusiastic mentors.

“When I joined Graham’s lab, everyone was eager to teach and support a new student,” she reflects. After watching Walker aid a struggling student, Wiltrout was further affirmed in her choice. “I knew I could go to Graham if I ever needed to.”

After graduation, Wiltrout taught molecular biology at Harvard for a few years until Baker facilitated her move back to MIT. Now, she’s a resource for faculty, postdocs, and students.

“She is an incredibly rich source of knowledge for everything from how to implement the increasingly complex tools for running a class to the best practices for ensuring a rigorous and inclusive curriculum,” says Iain Cheeseman, the Herman and Margaret Sokol Professor of Biology and associate head of the biology department.

Stephen Bell, the Uncas and Helen Whitaker Professor of Biology and instructor of the Molecular Biology series of MITxBio courses, notes Wiltrout is known for staying on the “cutting edge of pedagogy.”

“She has a comprehensive knowledge of new online educational tools and is always ready to help any professor to implement them in any way they wish,” he says.

Gordon finds Wiltrout’s experiences as a biologist and learning engineer instrumental to her own professional development and a model for their colleagues in science education.

“Mary Ellen has been an incredibly supportive supervisor. She facilitates a team environment that centers on frequent feedback and iteration,” says Tyler Smith, instructor for pedagogy training and biology.

Prepared for the pandemic, and beyond

Wiltrout believes blended learning, combining in-person and online components, is the best path forward for education at MIT. Building personal relationships in the classroom is critical, but online material and supplemental instruction are also key to providing immediate feedback, formative assessments, and other evidence-based learning practices.

“A lot of people have realized that they can’t ignore online learning anymore,” Wiltrout noted during an interview on The Champions Coffee Podcast in 2023. That couldn’t have been truer than in 2020, when academic institutions were forced to suddenly shift to virtual learning.

“When Covid hit, we already had all the infrastructure in place,” Baker says. “Mary Ellen helped not just our department, but also contributed to MIT education’s survival through the pandemic.”

For Wiltrout’s efforts, she received a COVID-19 Hero Award, a recognition from the School of Science for staff members who went above and beyond during that extraordinarily difficult time.

“Mary Ellen thinks deeply about how to create the best learning opportunities possible,” says Cheeseman, one of almost a dozen faculty members who nominated her for the award.

Recently, Wiltrout expanded beyond higher education and into high schools, taking on several interns in collaboration with Empowr, a nonprofit organization that teaches software development skills to Black students to create a school-to-career pipeline. Wiltrout is proud to report that one of these interns is now a student at MIT in the class of 2028.

Looking forward, Wiltrout aims to stay ahead of the curve with the latest educational technology and is excited to see how modern tools can be incorporated into education.

“Everyone is pretty certain that generative AI is going to change education,” she says. “We need to be experimenting with how to take advantage of technology to improve learning.”

Ultimately, she is grateful to continue developing her career at MIT biology.

“It’s exciting to come back to the department after being a student and to work with people as colleagues to produce something that has an impact on what they’re teaching current MIT students and sharing with the world for further reach,” she says.

As for Wiltrout’s own daughter, she’s declared she would like to follow in her mother’s footsteps — a fitting symbol of Wiltrout’s impact on the future of education.

No detail too small

For Sarah Sterling, the new director of the Cryo-Electron Microscopy facility at MIT.nano, better planning and more communication leads to better science.

Sarah Sterling, director of the Cryo-Electron Microscopy, or Cryo-EM, core facility, often compares her job to running a small business. Each day brings a unique set of jobs ranging from administrative duties and managing facility users to balancing budgets and maintaining equipment.

Although one could easily be overwhelmed by the seemingly never-ending to-do list, Sterling finds a great deal of joy in wearing so many different hats. One of her most essential tasks involves clear communication with users when the delicate instruments in the facility are unusable because of routine maintenance and repairs.

“Better planning allows for better science,” Sterling says. “Luckily, I’m very comfortable with building and fixing things. Let’s troubleshoot. Let’s take it apart. Let’s put it back together.”

Out of all her duties as a core facility director, she most looks forward to the opportunities to teach, especially helping students develop research projects.

“Undergraduate or early-stage graduate students ask the best questions,” she says. “They’re so curious about the tiny details, and they’re always ready to hit the ground running on their projects.”

A non-linear scientific journey

When Sterling enrolled in Russell Sage College, a women’s college in New York, she was planning to pursue a career as a physical therapist. However, she quickly realized she loved her chemistry classes more than her other subjects. She graduated with a bachelor of science degree in chemistry and immediately enrolled in a master’s degree program in chemical engineering at the University of Maine.

Sterling was convinced to continue her studies at the University of Maine with a dual PhD in chemical engineering and biomedical sciences. That decision required the daunting process of taking two sets of core courses and completing a qualifying exam in each field.

“I wouldn’t recommend doing that,” she says with a laugh. “To celebrate after finishing that intense experience, I took a year off to figure out what came next.”

Sterling chose to do a postdoc in the lab of Eva Nogales, a structural biology professor at the University of California at Berkeley. Nogales was looking for a scientist with experience working with lipids, a class of molecules that Sterling had studied extensively in graduate school.

At the time Sterling joined, the Nogales Lab was at the forefront of implementing an exciting structural biology approach: cryo-EM.

“When I was interviewing, I’d never even seen the type of microscope required for cryo-EM, let alone performed any experiments,” Sterling says. “But I remember thinking ‘I’m sure I can figure this out.’”

Cryo-EM is a technique that allows researchers to determine the three-dimensional shape, or structure, of the macromolecules that make up cells. A researcher can take a sample of their macromolecule of choice, suspend it in a liquid solution, and rapidly freeze it onto a grid to capture the macromolecules in random positions — the “cryo” part of the name. Powerful electron microscopes then collect images of the macromolecule — the EM part of cryo-EM.

The two-dimensional images of the macromolecules from different angles can be combined to produce a three-dimensional structure. Structural information like this can reveal the macromolecule’s function inside cells or inform how it differs in a disease state. The rapidly expanding use of cryo-EM has unlocked so many mechanistic insights that the researchers who developed the technology were awarded the 2017 Nobel Prize in Chemistry.

The MIT.nano facility opened its doors in 2018. The open-access, state-of-the-art facility now has more than 160 tools and more than 1,500 users representing nearly every department at MIT. The Cryo-EM facility lives in the basement of the MIT.nano building and houses multiple electron microscopes and laboratory space for cryo-specimen preparation.

Thanks to her work at UC Berkeley, Sterling’s career trajectory has long been intertwined with the expanding use of cryo-EM in research. Sterling anticipated the need for experienced scientists to run core facilities in order to maintain the electron microscopes needed for cryo-EM, which range in cost from a staggering $1 million to $10 million each.

After completing her postdoc, Sterling worked at the Harvard University cryo-EM core facility for five years. When the director position for the MIT.nano Cryo-EM facility opened, she decided to apply.

“I like that the core facility at MIT was smaller and more frequently used by students,” Sterling says. “There’s a lot more teaching, which is a challenge sometimes, but it’s rewarding to impact someone’s career at such an early stage.”

A focus on users

When Sterling arrived at MIT, her first initiative was to meet directly with all the students in research labs that use the core facility to learn what would make using the facility a better experience. She also implemented clear and standard operating procedures for cryo-EM beginners.

“I think being consistent and available has really improved users’ experiences,” Sterling says.

The users themselves report that her initiatives have proven highly successful — and have helped them grow as scientists.

“Sterling cultivates an environment where I can freely ask questions about anything to support my learning,” says Bonnie Su, a frequent Cryo-EM facility user and graduate student from the Vos lab.

But Sterling does not want to stop there. Looking ahead, she hopes to expand the facility by acquiring an additional electron microscope to allow more users to utilize this powerful technology in their research. She also plans to build a more collaborative community of cryo-EM scientists at MIT with additional symposia and casual interactions such as coffee hours.

Under her management, cryo-EM research has flourished. In the last year, the Cryo-EM core facility has supported research resulting in 12 new publications across five different departments at MIT. The facility has also provided access to 16 industry and non-MIT academic entities. These studies have revealed important insights into various biological processes, from visualizing how large protein machinery reads our DNA to the protein aggregates found in neurodegenerative disorders.

If anyone wants to conduct cryo-EM experiments or learn more about the technique, Sterling encourages anyone in the MIT community to reach out.

“Come visit us!” she says. “We give lots of tours, and you can stop by to say hi anytime.”

John Fucillo: Laying foundations for MIT’s Department of Biology

The Building 68 manager’s leadership, innovation, and laid-back attitude have helped to build a strong culture of community.

When you enter John Fucillo’s office at MIT, you will likely be greeted with an amiable nose boop and wagging tail from Shadow, a 4-year-old black lab, followed by a warm welcome from the office’s human occupant. Fucillo, manager of Building 68 — home to the MIT Department of Biology — is an animal lover, and Shadow is the gentlest of roughly nine dogs and one Siamese cat he’s taken care of throughout his life. Fortunately for the department, Shadow is not the only lab Fucillo cares for.

Fucillo came to MIT Biology in 1989 and says he couldn’t be happier. A Boston-area local, Fucillo previously spent two years working at Revere Beach, then learned skills as an auto mechanic, and later completed an apprenticeship with the International Brotherhood of Electrical Workers. As Building 68’s manager; environment, health, and safety coordinator; and chemical hygiene officer, Fucillo’s goal is to make workflows “easier, less expensive, more desirable, and more comfortable.” According to Mitchell Galanek, MIT radiation protection officer and Fucillo’s colleague for over 30 years, Fucillo was key for the department’s successful move into its new home when Building 68 was completed in 1994.

Throughout his time as a building manager, Fucillo has decreased routine spending and increased sustainability. He lowered the cost of lab coats by a whopping 92 percent — from $2,600 to $200 — with just one phone call to North Star, the building’s uniform/linens provider. Auditing the building’s plastic waste generation inspired the institute-wide MIT Lab Plastics Recycling Program, which now serves over 200 labs across campus. More than 50,000 pounds of plastic have been recycled in the last four years alone.

“John is not a cog in the wheel, but an integral part of the whole system,” says Anthony Fuccione, technical instructor and manager of the Biology Teaching lab.

Connecting and leading

Fucillo says one of his favorite parts of the job is chatting with researchers and helping them achieve their goals. He reportedly clocks about 10,000 steps per day on campus, responding to requests from labs, collaborating with colleagues, and connecting Biology to the Institute’s Environment, Health, and Safety (EHS) office.

“John is called upon — literally and figuratively — morning, noon, and night,” says Whitehead Professor of Molecular Genetics Monty Krieger. “He has had to become an expert in so very many areas to support staff, faculty, and students. His enormous success is due in part to his technical talents, in part to his genuine care for the welfare of his colleagues, and in part to his very special and caring personality.”

When MIT needed to comply with the Environmental Protection Agency’s decree to improve safety standards across campus, Fucillo sat on the committees tasked with meeting those standards while avoiding undue burden on researchers, establishing the Environmental Health and Safety Management system in 2002.

“From a safety perspective, that was one of the most challenging things MIT had to go through — but it came out at the end a better, safer, place,” says John Collins, EHS project technician and friend and colleague to Fucillo for over 20 years.

Fucillo later co-led the initiative for a 2011 overhaul of MIT’s management of regulated medical waste (RMW), such as Petri dishes, blood, and needles. Fucillo volunteered to pilot a new approach in Building 68 — despite a lukewarm response to the proposal from other biology EHS representatives, according to Galanek. This abundantly successful management system is now used by all MIT departments that generate RMW. It’s not only less expensive, but also does a better job at decontaminating waste than the previous management system.

“Anyone who has worked with John during his MIT career understands it is truly a privilege to partner with him,” Galanek says. “Not only does the work get done and done well, but you also gain a friend along the way.”

After consolidating a disparate group of individual lab assistants, Fucillo took on a supervisory role for the centralized staff tasked with cleaning glassware, preparing media, and ensuring consistency and sterility across Building 68 labs.

According to maintenance mechanic James (Jimmy) Carr, “you can’t find a better boss.”

“He’s just an easy-going guy,” says Karen O’Leary, who has worked with Fucillo for over 30 years. “My voice matters — I feel heard and respected by him.”

Looking forward

Although there are still many updates Fucillo hopes to see in Building 68, which will soon celebrate its 30th birthday, he is taking steps to cut back on his workload. He recently began passing on his knowledge to Facilities Manager and EHS Coordinator Cesar Duarte, who joined the department in 2023.

“It’s been a pleasure working alongside John and learning about the substantial role and responsibility he’s had in the biology department for the last three decades,” Duarte says. “Not only is John’s knowledge of Building 68 and the department’s history unparalleled, but his dedication to MIT and continued care and commitment to the health and well-being of the biology community throughout his career are truly remarkable.”

As he winds down his time at MIT, Fucillo hopes to spend more time on music, one of his earliest passions, which began when he picked up an accordion in first grade. He still plays guitar and bass nearly every day. When he rocks out at home more often, he’ll be leaving behind the foundations of innovation, leadership, and respect in Building 68.
