About me

  • Assistant Professor of Clinical Surgery

I have expertise in robotic and minimally invasive abdominal wall reconstruction and hernia repair, bariatric, and foregut surgery.

I did my general surgery residency training at Carolinas Medical Center in Charlotte, NC. I then completed an advanced minimally invasive surgery fellowship at the University of Alabama at Birmingham.

With an undergraduate background in electrical engineering, I have a particular interest in the latest technologies being used in gastrointestinal surgery. I am also passionate about surgical education, research, and global surgery.

My education and training

  • Medical School: Northwestern University Feinberg School of Medicine
  • Residency: Carolinas Medical Center
  • Fellowship: University of Alabama at Birmingham (UAB Hospital)
