Alexandra obtained her undergraduate degree in Chemical Engineering from The Cooper Union for the Advancement of Science an Art, and then her doctoral degree in Molecular Biophysics from The Rockefeller University. She conducted postdoctoral studies in the group of HHMI investigator, Dr. Niko Grigorieff, first at Brandeis University and later at the HHMI Janelia Farm Research Campus as a Damon Runyon Fellow. She is the recipient of a At the Interfaces Award from the Howard Hughes Medical Institute,  a Medical Research Award from The Rhode Island Foundation, a Salomon Faculty Research Award from Brown University, and awards from the German Society of Biochemistry, The International Brain Organization and Japan's Ministry of Education, Culture, Sports, Science and Technology. She is excited about structural biology, responses to stress and DNA damage, microtubules and things biochemical.

Amelie recently graduated from Reed College after studying biochemistry and molecular biology with a minor in film. She is excited about understanding how bacteria adapt to stressful environments by regulating gene expression across multiple levels. In the past, she has researched bacterial metal ion homeostasis and now she is interested in understanding the life cycle of global regulators of the bacterial stress response like RpoS. Outside of the lab, she enjoys reading old sci-fi novels, hanging around with her two cats, and getting outdoors.

Born and raised in Louisville, Kentucky, Lorenzo has just graduated from Brown with Bachelor of Arts degrees in Biology and Public Policy. Working in the Deaconescu lab allows him to explore his interest in biochemistry, structural biology, and cellular machinery. Beyond academics, Lorenzo enjoys running, watching soccer, and enjoying local restaurants with friends

Originally from Burundi, located in East Africa, Ange is a student at Brown University and is pursuing a Bachelor of Science in Biochemistry and Molecular Biology as well as a Certificate in Data Fluency. Influenced by her origins and the different people who populate her life, Ange has different interests that touch on tropical infectious diseases and tissue engineering, and likes to explore the ethical questions that these interests raise. Her research in the Deaconescu lab focuses on understanding the role of the Mfd protein in mutagenesis. In her spare time, Ange enjoys walking for hours admiring nature and dancing when there are no more restaurants to try, all three her favorite elements when it comes to exploring another culture.

Tammy  is invaluable to the lab and we could not do without her!
