Aparna Venkatesan is an Associate Professor and Department Chair in the Department of Physics and Astronomy at the University of San Francisco. Her scientific interests lie primarily in theoretical cosmology, including studies of the first stars and quasars in the universe, cosmological reionization (particularly helium reionization), cosmic element synthesis, the cosmic microwave background, the physics and chemistry of gas in the early universe, dark matter, and gravitational lensing. Her current work ranges from the aforementioned cosmology topics, to projects in the fields of dark stars and astrobiology.

In this clip of Strangest Weather on Earth, Professor Venkatesan explains what creates the "aurorae phenomena," as seen in the Northern Lights.
