Francesca Vallese, Ph.D

Assistant professor

CUNY Advanced Science Research Center, Structural Biology Initiative 

City College of New York, Department of Chemistry and Biochemistry

Francesca Vallese completed her studies at the University of Padova, Italy. During her PhD, she focused on studying the structure and interactions of proteins involved in hydrogen production. Her initial postdoctoral research was conducted in the laboratory of Prof. Giuseppe Zanotti, where she acquired expertise in purifying membrane proteins and X-ray crystallography. During her postdoc, she was a visiting student in Dr. Baumeister's lab at the Max Planck Institute of Biochemistry and collaborated with Novartis (Basel) and BioGUNE (Bilbao). As an Associate Research Scientist at Columbia University in Oliver Clarke's lab, she has become an expert in single-particle cryo-EM.

Francesca loves new adventures, and she is always ready for new challenges. In her free time she loves hiking and snorkeling and spend time in the nature.


Sebastiano Nigris, Ph.D

Research Assistant - Lab Manager

Sebastiano graduated in Biotechnology and earned his PhD in Evolutionary Biology at the University of Padova (Italy), where he studied plant-microbe interactions with a focus on the effects of beneficial bacteria on root structure. After his PhD, he moved to the Botanical Garden of Padova to investigate the molecular pathways involved in ovule and seed development in Ginkgo and other gymnosperms, gaining considerable experience in plant cell biology and evolutionary developmental biology studies. He also explored the molecular effects of plant microbiota on root development to create biofertilization strategies for more sustainable agriculture. His research philosophy is, “Nothing in Biology Makes Sense Except in the Light of Evolution”. Sebastiano loves plants and flowers and enjoys traveling and reading good books.
