We are currently seeking a Postdoctoral Associate within the lab of Dr. Kim Orth at UT Southwestern Medical Center location. The Orth lab is interested in deciphering molecular mechanisms used for signaling by the host and pathogen. We are interested in elucidating the activity of virulence factors from pathogenic bacteria so that we can gain novel molecular insight into eukaryotic signaling systems. In the past, we have discovered mechanisms such as Ser/Thr acetylation, AMPylation, irreversible actin assembly, bacterial phosphoinositide-binding domain mimics, and pore-forming V-ATPase inhibitors. The marine bacterium Vibrio parahaemolyticus is the worldwide leading cause of seafood-borne acute gastroenteritis. For decades, this pathogen has been studied exclusively as an extracellular bacterium. However, recent studies from our lab have revealed the pathogen's ability to invade and replicate within host cells. We find novel mechanisms used by the pathogen to manipulate and exploit host signaling mechanisms so this bacterium can survive, proliferate, and escape. Our work at UT Southwestern is accomplished using a broad range of tools, including biochemistry, molecular microbiology, protein chemistry, structural biology, yeast genetics, cell biology and more. Details on our research interests and past publications can be found at:

The Orth lab is an exciting, friendly, welcoming, and inclusive place. Some of our future studies include, but are not limited to, deciphering mechanisms involved in bacterial pathogenesis and signaling mediated by mammalian AMPylation machinery. We currently have many projects available to decipher virulence mechanisms and to elucidate the AMPylation rheostat for the unfolded protein response using genetic mouse and fly models.

Applicants should submit their curriculum vitae, a one-page statement on how their experience and interests relate to our work - tell us why you are interested in the Orth lab and what you would want to work on based on our publications- and contact information for three references.
