HEMI Fellow Sarah Hörst receives 2022 President’s Frontier Award

In a surprise virtual presentation, JHU President Ron Daniels presented the award to Alexis Battle, an associate professor in the Department of Biomedical Engineering, and Sarah Hörst, HEMI Fellow and an associate professor in the Department of Earth and Planetary Sciences. Both researchers will receive $250,000 to pursue new lines of research, expand their laboratories, or support their lab members.

“Let me take this moment to say how dazzled we were, Alexis and Sarah, by the ambitions and scope of your research and how highly your colleagues, mentors, and students regard each of you,” said Daniels in the virtual presentation. “Having a way to honor those qualities in our faculty was a reason why we created this amazing award eight years ago. … You both join a cadre of truly remarkable people from across all our divisions whose work truly stands apart.”

The President’s Frontier Award was originally launched with a commitment of $2.5 million from trustee Louis J. Forster, A&S ’82, SAIS ’83, and is now paired with a $1 million donation from alumnus David Smilow, A&S ’84. Winners have spanned the university’s divisions and included molecular biologist Andrew Holland (2021), mathematician Emily Riehl (2020), astrophysicist Brice Ménard (2019), nephrologist and epidemiologist Deidra Crews (2018), composer Michael Hersch (2017), molecular biologist Scott Bailey (2016), and stem cell research Sharon Gerecht (2015).

The award typically recognizes one winner and one finalist each year, but Battle and Hörst were both selected this year based on the strength of their applications and the demonstrated impact and continued potential of their work.

“The two of you embody in some sense the incredible breadth of research that goes on at JHU,” said Ed Schlesinger, dean of the Whiting School of Engineering. “From the very smallest genetic materials that define what life is all about to the planets, space, the cosmos, and the search for life beyond our own world—there is something particularly poetic about the juxtaposition of both of [your work].”

Hörst, a planetary scientist, studies the composition and characteristics of aerosols in the atmospheres of early Earth and other planets. Using laboratory experiments, modeling, and remote sensing and in situ measurements of atmospheric chemistry, Hörst and her lab work to understand how small molecules transition to become aerosols and the resulting physical and chemical properties of those particles.

The work has implications for assessing the habitability of other planets and for the search for life beyond our solar system. Under the right conditions, adding energy to simple mixtures of common gases can produce much more complex molecules like amino acids, which form the building blocks of living organisms.

Essential to her work is her groundbreaking approach to laboratory science. Using a custom-built Planetary Haze Research lab—a one-of-its-kind experimental lab—Hörst and her group simulate the chemical reactions that contribute to the formation of aerosols in planetary atmospheres. With this approach, she can experiment with a vast range of temperatures (90-800 degrees Kelvin, or -297-980 degrees Fahrenheit) and can use different energy sources to initiate chemical reactions across a variety of atmospheric gases and conditions. Her lab is the first in the world to be dedicated to studying photochemical haze production in exoplanet environments, and she has published research on Saturn, Saturn’s moon Titan, and early Earth.

Hörst’s work is directly relevant to important space missions, including two upcoming NASA missions: Dragonfly, which will investigate prebiotic organic chemistry and habitability on Saturn’s largest moon, Titan; and DAVINCI+, which will probe the chemical composition of the atmosphere of Venus.

“Particularly impressive is her ingenuity and creativity in developing and leading a new scientific field essentially from scratch: extrasolar planet atmosphere laboratory studies,” wrote Sabine Stanley, a Bloomberg Distinguished Professor and chair of the Department of Earth and Planetary Sciences, in a letter nominating Hörst for the award. “Her work has already had major impact on the global effort to observe and characterize exoplanet atmospheres.”

She received the 2020 LAD Early Career Award from the American Astronomical Society’s Laboratory Astrophysics Division and the prestigious 2020 James B. Macelwane Medal from the American Geophysical Union, widely considered the highest honor for early career scientists in the field of geological and planetary sciences. She received a Johns Hopkins Catalyst Award in 2017 and was a co-investigator on a Discovery Award led by Maya Gomes in 2020.

Hörst received two bachelor of science degrees—one in planetary science and one in literature—from the California Institute of Technology. She received her PhD in planetary sciences from the University of Arizona, Tucson. She joined Johns Hopkins in 2014 and currently mentors three graduate students, two postdoctoral research fellows, and an associate research scientist.

Chris Celenza, dean of the Krieger School of Arts and Sciences, gave Hörst particular praise for her emphasis on mentorship and collegiality.

“I often think that we are at our best in the arts and sciences when we’re reciprocally reinforcing conversations among faculty, postdocs, graduate students, and undergraduates,” Celenza said during the award presentation. “I know in your lab, you’ve cultivated that very type of engagement, so I want to thank you, deeply, for all you have done for this wonderful Department of Earth and Planetary Sciences and for Johns Hopkins and for the Krieger School.”

Hörst’s dedication to her lab members was evident from the moment they “Zoom bombed” the meeting, joining in on the coordinated surprise. “When I saw the names popping up on the screen, all I could think was how much more great science the people who are already working with me are going to get to do,” Hörst said through tears. “And that means the absolute world to me.”

HEMI Mourns the Passing of Mark Robbins

Mark O. Robbins, HEMI Fellow and professor in the Department of Physics and Astronomy, died unexpectedly on Thursday, August 13, 2020.

Robbins was a member of the HEMI’s Executive Committee and a significant contributor to the research in the MEDE program. He was one of the world’s leading authorities on the mechanisms of friction, granular flow, the mechanics of earthquakes, polymer rheology and molecular dynamics. Within MEDE, he played a dominant role in the modeling aspects of the Polymers CMRG, and more recently in the modeling of granular flow within the Ceramics CMRG. His legacy in the physics of disordered matter is very substantial, and his legacy in terms of the people that he mentored is stronger still.

He also is known for his research regarding the atomic origin of macroscopic phenomena such as earthquakes and avalanches and his help in leading the establishment of major computer facilities at Johns Hopkins University.

Read a full remembrance of Prof. Robbins.

Soojung Claire Hur selected to attend Frontiers of Engineering Symposium

Soojung Claire Hur, the Clare Booth Luce Assistant Professor of Mechanical Engineering, has been invited by the National Academy of Engineering (NAE) to attend the 2020 Japan-America Frontiers of Engineering Symposium (JAFOE). The event will be held June 22-24 in Irvine, California.

Organized by the NAE and the Engineering Academy of Japan, the symposium will bring together 60 outstanding early-career Japanese and American engineers to discuss research and technical work in various engineering disciplines. The participants – from industry, academia, and government – were nominated by fellow engineers or organizations.

This year’s iteration will cover cutting-edge developments in four areas: Blockchain, Mitigating Sea Level Rise, Machine Learning and AI for Mental Health, and Soft Robotics. Each participant will be asked to present a poster describing their work.

Hur looks forward to an unparalleled opportunity to meet emerging engineering leaders and potential collaborators.

“Meeting new people often inspires a brilliant new idea for a researcher. This symposium is a great venue for creative brainstorming and building a strong professional network, two things I really enjoy,” said Hur. “The excitement I feel when casual conversations with fellow researchers lead to synergic collaborations for a new, unexpected, fruitful research project is what keeps me pursuing an academic career.”

Hur develops microfluidic platforms to understand complex fluid dynamics principles and to translate acquired knowledge into practical application. In particular, she is interested in studying single-cell mechanics and understanding the veiled correlations between cellular functions and their physical phenotypes. Using this research, Hur has developed instruments to facilitate simple and cost-effective biological assays, with applications in oncology, immunology, gene therapy, and regenerative medicine.

Most recently, Hur received a Career Catalyst Research Grant from the Susan G. Komen Foundation to develop a device that can collect and genetically modify tumor cells from the blood samples of metastatic breast cancer patients. These purified and modified cells will enable scientists to monitor the patient’s cancer progression in a lab, and to develop and test personalized treatment plans.

“My goal is set to build systems that enable inexpensive, early disease diagnostics and provide accurate information for basic and clinical researchers to test their hypotheses. I grapple with highly interdisciplinary questions. I will significantly benefit from interactions with professionals attending the Frontiers workshop, who may have different perspectives, to discover innovative approaches that might not be possible alone,” adds Hur.

Hur received her bachelor’s, master’s and doctoral degrees in mechanical engineering from the University of California, Los Angeles. She is a fellow of the Hopkins Extreme Materials Institute, an associate researcher at the Johns Hopkins Institute for NanoBioTechnology, and holds a secondary appointment in the Department of Oncology at the Johns Hopkins University School of Medicine. She joined the Hopkins faculty in 2015.

HEMI Fellow Michael Shields Receives DOE Early Career Award

HEMI Fellow Michael Shields (assistant professor, Dept. of Civil Engineering) has been selected by the U.S. Department of Energy Office of Science to receive a five-year grant under the agency’s Early Career Research Program.

Shields’ project, titled, “Low-dimensional Manifold Learning for Uncertainty Quantification in Complex Multi-scale Stochastic Systems” leverages large-scale so-called dimension hyper-reduction methods to enable uncertainty quantification for complex multi-scale systems. The advanced modeling approach is likely to be more computationally manageable than conventional methods, allowing for potentially significant impacts in far-ranging fields from computer vision, to language processing, data analysis/machine learning and clustering, and complex networks such as infrastructure and/or communication systems because they afford a fundamental ability to learn from the intrinsic structure of high-dimensional data on the Grassmannian, which is widely recognized as important in these fields. The research developments proposed will also lead to advanced software solutions such as the UQpy open-source Python toolbox for large-scale uncertainty quantification in multiscale stochastic systems.

The DOE Early Career Research Program, now in its tenth year, is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work. To learn more about the award and view information from the other 2019 awardees, click here.

This is Shields’ third young investigator award. He is also the recipient of the National Science Foundation Early CAREER Award and the Office of Naval Research Young Investigator Award.
