The direct conversion of methane gasoline to liquid methanol on the web site the place it’s extracted from the Earth holds monumental potential for addressing a lot of important environmental issues. Creating a catalyst for that conversion has been a vital focus for Affiliate Professor Heather Kulik and the lab she directs at MIT.
As necessary as that analysis is, nevertheless, it is only one instance of the innumerable prospects of Kulik’s work. In the end, her focus is much broader, the scope of her exploration infinitely extra huge.
“All of our analysis is devoted towards the identical sensible objective,” she says. “Specifically, we goal to have the ability to predict and perceive utilizing computational instruments why catalysts or supplies behave the best way they accomplish that that we are able to overcome limitations in current understanding or current supplies.”
Merely put, Kulik desires to use novel simulation and machine-learning applied sciences she and her lab have developed to quickly examine the sprawling world of potential chemical combos. Within the course of, the staff is mapping out how chemical constructions relate to chemical properties, to be able to create new supplies tailor-made to specific functions.
“When you understand the sheer scale of what number of supplies we might or must be learning to resolve excellent issues, you understand the one strategy to make a dent is to do issues at a bigger and sooner scale that has ever been finished earlier than,” Kulik says. “Because of each machine-learning fashions and heterogeneous computing that has accelerated first-principles modeling, we at the moment are in a position to begin asking and answering questions that we might by no means have addressed earlier than.”
Regardless of Kulik’s many awards and constant recognition for her analysis, the New Jersey native was not all the time destined to be a scientist. Her mother and father weren’t significantly inquisitive about math and science and, though she was mathematically precocious and did arithmetic as a toddler and college-level lessons in center faculty, she pursued different pursuits into her teenagers, together with inventive writing, graphic design, artwork, and pictures.
Majoring in chemical engineering on the Cooper Union, Kulik says she needed to occupy her thoughts, do one thing helpful, and “make an okay residing.” Chemical engineering was one of many highest-paying professions for undergraduates, she says.
The very first thing she remembers listening to about graduate faculty was from a instructing assistant in her undergraduate physics class, who defined that being in academia meant “not having an actual job till you’re at the very least 30” and dealing lengthy hours.
“I assumed that seemed like a horrible concept!” Kulik says.
Fortunately, a few of her classroom experiences on the Cooper union, in addition to encouragement from her quantum mechanics professor, Robert Topper, led her towards analysis.
“Whereas I needed to be helpful, I saved being drawn to those elementary questions of how realizing the place the atoms and electrons had been positioned defined the world round us,” she says. “In the end, I obtained my PhD in computational supplies science to develop into a scientist who works with electrons day by day for that motive. Since what I do infrequently appears like a chore, I now have a larger appreciation for the truth that this path allowed me to ‘not have an actual job.’”
Kulik credit MIT professor of chemistry and biology Cathy Drennan, whom Kulik collaborated with throughout graduate faculty, with “serving to me see previous the short-term obstacles that come up in academia” and “exhibiting me what a profession in science might appear to be.” She additionally mentions Nicola Marzari, her PhD advisor, then an affiliate professor within the MIT’s Division of Supplies Science and Engineering, and her postdoc advisor at Stanford College, Todd Martinez, “who gave me a glimpse of what an impartial profession may appear to be.”
Kulik works exhausting to cross on her ethics and her concepts about work-life stability to college students in her lab, and she or he teaches them to depend on one another, referring to the group as a “tight-knit neighborhood all with the identical objectives.” Twice a month, she holds conferences at which she encourages college students to share how they’ve provide you with options when working via analysis issues. “We are able to every see and study from completely different problem-solving methods others within the group have tried and assist one another out alongside the best way.”
She additionally encourages a light-weight ambiance. The lab’s net web page says its members “embrace very #random (however in all probability pretty uncool) jokes in our Slack channels. We’re computational researchers in spite of everything!”
“We wish to maintain it lighthearted,” Kulik says.
Nonetheless, Kulik and her lab have achieved main breakthroughs, together with altering the strategy to computational chemistry to make the best way multiscale simulations are arrange extra systematic, whereas exponentially accelerating the method of supplies discovery. Over time, the lab has developed and honed an open-source code referred to as molSimplify, which researchers can use to construct and simulate new compounds. Mixed with machine-learning fashions, the automated methodology enabled by the software program has led to “structure-property maps” that designate why supplies behave as they do, in a extra complete method than was ever earlier than potential.
For her efforts, Kulik has gained grants from the MIT Power Initiative, a Burroughs Wellcome Fund Profession Award on the Scientific Interface, the American Chemical Society OpenEye Excellent Junior College Award, an Workplace of Naval Analysis Younger Investigator Award, a DARPA Younger College Award and Director’s Fellowship, the AAAS Marion Milligan Mason Award, the Bodily Chemistry B Lectureship, and a CAREER award from the Nationwide Science Basis, amongst others. This yr, she was named a Sloan Analysis Fellow and was granted tenure.
When not exhausting at work on her subsequent accomplishment, Kulik enjoys listening to music and taking walks round Cambridge and Boston, the place she lives within the Beacon Hill neighborhood together with her associate, who was a fellow graduate scholar at MIT.
Every year for the previous three to 4 years, Kulik has spent at the very least two weeks on a wintertime trip in a sunny local weather.
“I mirror on what I’ve been doing at work in addition to what my priorities is perhaps each in life and in work within the upcoming yr,” she says. “This helps to tell any choices I make about easy methods to prioritize my time and efforts every year and helps me to verify I’ve put every part in perspective.”
