Christina Francis, a born and raised New Yorker, graduated with honors from Johns Hopkins University in Spring 2021 with a B.S. in Environmental Science. Throughout her undergraduate career, she spent every semester and summer gaining research experience in various fields of study that fall under the umbrella of environmental science to expose herself to an array of subdisciplines. Some of those research experiences include a hydrology project estimating volume changes of a stormwater retention basin at Unity College in Maine; an ecology project determining the non-consumptive effects of predator presence on the eastern oyster in New York City waters; a microbiology project examining correlations between soil nematode reproductive organ structure and population dynamics; and another ecology project improving long term ecological forecasts. While participating in Stanford’s Summer Undergraduate Research in Geoscience and Engineering (SURGE) Program, she conducted a study that analyzed the effects of oil and gas well site activity on air pollutant concentrations in California. She adapted this project into a senior thesis, which investigated the contribution of a local incinerator to downwind concentrations of nitrogen oxides and particulate matter in Baltimore City, Maryland. Through these latter research experiences, she began to develop an affinity for atmospheric sciences and is excited to continue exploring this subject further via the modeling of tropical cyclones. As a Bridge Scholar, Christina is working under the guidance of Prof. Suzana J. De Camargo in the Division of Ocean and Climate Physics (Lamont-Doherty Earth Observatory). After completing the Bridge Program, Christina intends to pursue her graduate studies in the environmental sciences with a focus on atmospheric sciences.

Alexis Kim was born to two Cambodian refugees and raised in Lowell, Massachusetts. After taking an introductory biology course in high school, she became fascinated with the biological sciences and medicine. This fascination led her to pursue a Bachelor of Science at the University of Massachusetts (UMass), Amherst, where she majored in biochemistry and molecular biology. After taking a neurobiology course at UMass, her curiosity about neuroscience led her to join Karine Fenelon’s laboratory in the summer of 2019 under the William Lee Science Impact Program (Lee SIP). As a Lee SIP scholar, Alexis tested the efficacy of optogenetics using electrophysiological field recordings. From there, Alexis continued to work with Dr. Fenelon in the fall to conduct a year-long research project that investigated the significance of the hippocampus in sensorimotor gating using prepulse inhibition (PPI) in a murine model system. Abnormal or impaired PPI has been linked to patients with schizophrenia, obsessive-compulsive disorder, and Huntington’s disease. In conjunction with this project, Alexis also joined the laboratory of Dong Wang, after completing his biochemistry course. In this group, she investigated the mechanism of nitrogen-fixing symbiosis amongst legumes and bacteria, using CRISPR Cas-9 genome engineering systems. Alexis worked in these two laboratories until May of 2020 when she became the first in her family to graduate from university. Currently, Alexis is working under the mentorship of Bianca Jones Marlin at the Mortimer B. Zuckerman Mind Brain Behavior Institute. Her research focuses on understanding the transgenerational epigenetic inheritance of trauma and neuromodulation. After completing the Bridge to the Ph.D. Program in STEM, Alexis plans to continue her graduate studies in neuroscience where she is looking to combine the intersectionality of engineering, medicine, and natural science.
