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.

Originally from Woodside, California, Sophia is a sophomore at Brown University planning to concentrate in biochemistry and molecular biology. Sophia plays for the Brown Women’s Water Polo team and is an avid baker and dog-lover. Sophia is focusing on how bacteria adapt to phosphate starvation.

Rebecca Kim

Undergraduate Researcher



Phone: (401) 863-6729


I grew up in both New Jersey and South Korea, and now I am studying for my ScB in Biochemistry and Molecular Biology at Brown University. I developed an interest in structural biology during a summer internship working in the Tsai Lab at the Baylor College of Medicine. In my free time, I like to swim, draw, and ride my cruiser! I have a strong interest in ClpXP biology.

Ketan is a sophomore at Brown University planning on concentrating in computational biology and art history. He is originally from Dallas, Texas and in his free time he enjoys martial arts, acrobatics, and basketball. In the lab, he likes playing with ClpXP adaptors!

Ange Karondo

Undergraduate Researcher



Phone: (401) 863-6729


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.
