Hello and welcome to Speaking of Psychology, a podcast produced by the American Psychological Association.

I'm your host, Kim Mills.

Speaking of Psychology is a podcast for anyone with an interest in the science of psychology.

We talk to psychological researchers, practitioners, and educators about any and every aspect of psychology and its application

to the world around us. Dr. Sharut Guntuku is a postdoctoral researcher in multimedia computing,

working at the Penn Medicine Center for Digital Health. His research aims to leverage large-scale

social media image and text data to model social

health outcomes and psychological traits.

He also works closely with the World Well-Being Project at the Positive Psychology Center

at the University of Pennsylvania.

Before joining the Penn Medicine Center, Dr. Guntuku completed his PhD studies on modeling

users' personality and multimedia preferences at the School of Computer Science and Engineering

at Nanyang Technological University in Singapore. He also worked on facial expression recognition

while interning at Panasonic. Thank you for joining us today.
