Rafael Colón was born in Elizabeth, New Jersey, and raised in the West Village, New York City. Rafael attended Lehman College of the City University of New York (CUNY), where he obtained a B.S. in physics. As an undergraduate, Rafael participated in AstrocomNYC, a partnership between CUNY, American Museum of Natural History and Columbia University supported by the National Science Foundation (NSF). There, his research with Luis Anchordoquí investigated the origin of ultra-high-energy cosmic rays. In collaboration with the Pierre Auger Observatory in Argentina, Rafael and his research team proposed a model whereby dormant quasars could propagate cosmic-ray nuclei up to ultra-high energies. Rafael co-authored the resulting paper, published in the Journal of High Energy Astrophysics. This experience sparked Rafael's interest in high-energy astrophysics. At Columbia University, Rafael worked with Lorenzo Sironi, using particle-in-cell simulations to study the effects of magnetic reconnection in the gamma-ray flares originating from the Crab Nebula. Rafael plans to continue exploring the high energy universe and pursue a Ph.D. in astrophysics.

Advisor: Simon Billinge
Neno Fuller graduated from Brooklyn College of the City University of New York (CUNY) in 2015 with a B.S. in physics and a minor in mathematics. In 2013, Neno worked with Nancy Griffeth, comparing different computational models of the Ras-protein mediated cell-signaling pathway to develop therapies targeting mutations that affect this pathway. Starting in 2014, he was a Louis Stokes Alliance for Minority Participation scholar in the laboratory of Mim Nakarmi, where he grew thin-film hexagonal boron nitride by means of chemical vapor depositions and atomic-force microscopy for photonic applications. Also in 2014, Neno was a REU student in Andrew Houck’s group in Princeton University’s Department of Electrical Engineering. He used a high-frequency structure simulator to model a filter device for use in quantum computing. Back at Brooklyn College, Neno’s senior thesis with Karl Sandeman focused on the magnetocaloric effect, a phenomenon whereby a material in a magnetic field experiences a change of temperature when the field is changed. Magnetic refrigeration employs this effect to generate a cycle akin to the gas-based cooling of traditional refrigeration, which relies on hydro-fluorocarbons that have 2000 times the global warming potential of CO2. In Simon Billinge’s group, Neno investigated the magnetocaloric properties of Manganese-Iron-Silicon, which is particularly promising because of its cheap and non-toxic components. By comparing the structural features of three samples over two thermal cycles, Neno aimed to clarify the link between structure and the thermal-history dependence of this material’s magnetic properties.
*Neno plans to pursue a Ph.D. in physics in the near future.

In September 2015, Jazmine moved to Columbia University and joined the Prives laboratory, whose focus is the protein p53. p53 is a tumor-suppressor at the center of many regulatory pathways responsible for maintaining balance in the cell, and is frequently mutated in human cancers. Jazmine investigated the role of a point mutation (A347D) that causes p53 to shift from its active (tetrameric) form to its inactive (dimeric) form. She sought to elucidate the possible different roles of dimeric p53 in the cell by overexpressing the dimer mutant (A347D) in cancer cells and by observing the effects of the naturally-occurring mutation in patient cells.

Christopher Medina-Kirchner, a native of Milwaukee, Wisconsin, graduated from the University of Wisconsin-Milwaukee in 2014 with a B.A. in psychology. As an undergraduate, he was a McNair scholar and conducted research in Krista Lisdahl’s Brain Imaging and Neuropsychology (BraIN) Laboratory, as well as with the Milwaukee County Drug Treatment Court evaluation team. Through this work, Christopher began to notice how misinformation about the neuropsychopharmacological effects of drugs has contributed to high incarceration rates. This inspired him to gain a more thorough understanding of the neurobiological and environmental factors that determine responses to drug effects. At Columbia, Christopher worked with Carl Hart to understand factors that mediate drug self-administration behavior and with Geraldine Downey to develop a rejection-sensitivity model of coping with the stigma of a criminal record. He received a “Beyond the Bars” fellowship, which affords him an opportunity to participate in research projects aimed at increasing our understanding of mass incarceration and factors that will reverse this situation. Christopher aspires to become a neuropsychopharmacologist who investigates the effects of psychoactive substances in human research patients while taking into consideration environmental and social factors.

In addition, he examined the correlation between race and masculinity and their affiliation to stereotype threat. Brian received his B.A. in psychology from Argosy University in Chicago, Illinois, in the spring of 2010. Before graduating, Brian was a McNair Scholar at Michigan State University. There he investigated the impact of race and rank in sexual harassment in men in the military and the sexual harassment of working women with Isis Settles and NiCole Buchanan. In addition, Brian founded a nonprofit organization that works with at-risk youths and is dedicated to bridging educational gaps and assisting minority males in the transition to adulthood. Brian plans on obtaining his Ph.D. in clinical psychology.
Kirsten is from Pelham, New York, and received her B.A. in psychology from Connecticut College in May 2010. As an undergraduate, she did research under the mentorship of Emery Brown at Massachusetts General Hospital, where she examined the actions of general anesthetic drugs and how they induce loss of consciousness. It was this experience that ignited Kirsten's interest in pharmacology. During her time in the Bridge Program, Kirsten worked with Kevin Ochsner studying the regulation of craving in methamphetamine users and with Carl Hart to investigate how ketamine affects cocaine users. In particular, Kirsten looked at whether ketamine reduces cue reactivity (the intensity of response to drug cues), and whether it enhances motivation to change patterns of drug use. This may help determine whether ketamine can be used in treatments for cocaine dependence.
* In 2018, Kirsten received a Ph.D. in psychology from Columbia University and is now working as a medical writer at LifeSci Communications.

A native of Edo, Nigeria, Egbe moved to the United States in 2003. As an undergraduate at Saint John's University, she became a McNair Scholar, and did research under the mentorship of Richard Lockshin. In the Lockshin laboratory, Egbe worked on zebrafish embryos to better understand the implications of caspase-3 in cell death. As a Bridge scholar, Egbe detected unknown (non-apoptotic) cell deaths via staining and antibody assays in the developmental stages of mice embryos. This work may pave way for a better understanding of the behavior of cancer cells, as distortion of/disruption in cell death pathways have been implicated in cancers and other neuronal diseases. In addition, she worked to develop biomarkers for erastin, a potential anti-cancer drug that was developed in the Stockwell laboratory. Egbe plans to obtain an M.D./Ph.D. with a focus in cancer and pharmacological research.

Khatera was born in Kabul, Afghanistan, and grew up in Queens, New York. She received her B.S. in biology and B.A. in environmental studies from Brooklyn College (CUNY). As an undergraduate, Khatera worked with Thomas Lewandowski studying the toxicological effects on a cultured cell line of the combined exposure to lead and mercury. As a Bridge scholar, Khatera researched a covalent modification of connexin43 (Cx43), a protein subunit of cellular gap junctions, which allow passage of small molecules between adjacent cells. Gap junctions built from Cx43 are required for development and homeostasis of higher organisms, and mutations in the Cx43 gene are known to cause human disease. Like many cytoplasmic proteins, connexins undergo covalent modification of their coded amino acids following protein synthesis. Khatera studied Cx43 post-translational modifications, which may elucidate further required determinants of gap junction structure and function.
* In 2017, Khatera received a Ph.D. in toxicology from the University of Rochester and is now a senior toxicologist at Conagra Brands.
