DNA, Genetics, and DNA Barcoding

April 15th, 2021

Have you ever wondered how scientists use DNA and genetics to learn about organisms? How do genes affect our traits and behaviors? How do scientists use DNA to identify people, plants, or animals? Join BioBus live on April 15th at 4pm ET for our Student Town Hall on DNA, genetics, and DNA barcoding. Our special guests, Dr. Daniel Cabrera and Dr. Mark Stoeckle, will answer YOUR questions! Submit your questions now!

Guest Speakers

Dr. Daniel Cabrera

Neuroscientist and Resident Doctor

Dr. Daniel Cabrera is a MD-PhD student at Weill Cornell Medical College and The Rockefeller University. Originally from Colombia, he moved to New York to complete his undergraduate degree at Columbia University. He specializes in neuroscience and genetics, and he is interested in understanding how behaviors like feeding can affect genes that determine longevity in organisms like fruit flies. In his free time, Dr. Cabrera enjoys mentoring new generations of scientists, working out, and spending time with family and friends.

Dr. Mark Stoeckle

Geneticist

Dr. Mark Stoeckle is a Senior Research Associate in the Program for the Human Environment at The Rockefeller University. Dr. Stoeckle’s research interests are DNA, the environment, and communicating scientific information through graphics. He helped organize the DNA Barcoding Initiative and his research projects with students in New York City have been covered in the New York Times, Washington Post, and the Wall Street Journal. Dr. Stoeckle is currently using environmental DNA to monitor ocean life and track fish diversity along the mid-Atlantic coast.
