Biology is fundamental to our changing world. The 21st century challenge for our students, our scholars, and the greater society is to understand our place in this changing world and to create fundamental knowledge for informed policies, economies, and social structure.

Upcoming Events

Cross-kingdom RNAi and extracellular vesicle-mediated small RNA trafficking between plants and fungal pathogens with Hailing Jin


Small RNAs (sRNAs) are short non-coding RNAs that mediate gene silencing in many cellular processes. We discovered that some sRNAs from eukaryotic pathogens, such as Botrytis cinerea, can move into host…

The neural control of adaptive behavior


Survival requires responding to constantly changing conditions. Over time, evolution has selected for neural circuits that ensure robust and adaptive responses to survival needs. My lab is focused on uncovering the…

Intra-genomic conflict and the preservation of genome integrity with Mia Levine


Selfish DNA elements infest eukaryotic genomes. These “genome parasites” act akin to viruses, hijacking our cell’s machinery to increase their copy number in the host genome. Such selfish element proliferation can…

Due the COVID-19 epidemic, the University of Pennsylvania has limited on-campus activities. As such, our team will be working remotely until further notice. If you need assistance, please send an email to biology@sas.upenn.edu, and we will happily assist you in a virtual format. For immediate service during normal working hours (M-F, 9am to 5pm) our phones are operational.

Stay safe and take care.
