Daniel P. Kelly

Dr. Kelly’s research career began with deciphering the genetic basis of inborn errors in metabolism in children, followed by a series of breakthrough discoveries relevant to the diagnosis and treatment of common forms of heart failure in the general population.

Judith R. Kelsen, MD

Judith R. Kelsen

Dr. Kelsen’s research focus is on the genetic, immunologic, and microbiomic causes of very early onset inflammatory bowel disease. Through a multidisciplinary team approach, Dr. Kelsen and her colleagues perform genetic sequencing to identify causative genetic variants in children with VEO-IBD, study the function of these variants, and use this information to improve the clinical outcomes for these children.

Benjamin C. Kennedy, MD

Benjamin C. Kennedy

Dr. Kennedy's current research focuses on epilepsy genetics and epilepsy surgery, including stereo-EEG, hemispherotomy, corpus callosotomy, and vagal nerve stimulation.

Chén C. Kenyon, MD, MSHP

Chén C. Kenyon

Dr. Kenyon's research focuses on integrating care systems and reducing outcome disparities for children with asthma. His recent work focuses on developing novel interventions to enhance asthma controller medication use in the highest risk children by leveraging mobile health technology and incentives oriented to the child.

Ron Keren, MD, PhD

Ron Keren

Dr. Keren’s research focuses on the effectiveness and cost-effectiveness of treatments for common problems in general pediatrics, including the prediction and prevention of newborn hyperbilirubinemia (jaundice) and kernicterus (a complication of jaundice), the therapeutic and radiological management of children with urinary tract infections, and the epidemiology and economics of influenza.

Leslie S. Kersun, MD, MSCE, MSEd

Leslie S. Kersun

Dr. Kersun has a strong interest in trainee education and collaborates with colleagues at Children's Hospital of Philadelphia and other institutions to develop innovative methods of teaching various topics in oncology. She also engages in collaborative research related to the communication of difficult news to patients.

Sudha K. Kessler, MD, MSCE

Sudha K. Kessler

Dr. Kessler is interested in the epileptic mechanisms of the human brain, specifically in children and the effect that transcranial magnetic stimulation has on those neural processes.

Todd J. Kilbaugh, MD

Todd J. Kilbaugh

Todd Kilbaugh, MD, is an anesthesiologist and pediatric intensivist with the Department of Anesthesiology and Critical Care Medicine, medical director of the ECMO Center, and director of the Resuscitation Science Center at Children's Hospital of Philadelphia. 

Mina Kim, PhD, NCSP

Mina Kim

Dr. Kim conducts clinical evaluations for infants and school-age children for studies exploring language and development. Her work at the Center for Autism Research focuses on developing and implementing behavioral protocols to support children who are participating in neuroimaging research studies.

Thomas F. Kolon, MD

Thomas F. Kolon

Dr. Kolon is an expert in the care of children with genital disorders and renal/bladder/prostate cancers. His expertise in pediatric urologic oncology includes optimizing organ-sparing surgery and preservation of fertility in oncology patients.

Eiki Koyama, DDS, PhD

Dr. Koyama's research focuses on Hereditary Multiple Exostoses (HME), a genetic disorder that causes the development of multiple benign tumors on the surface of the metaphyses of long bones. Based on his extensive knowledge of the normal processes of skeletal development and growth, Dr. Koyama's research aims to clarify the molecular mechanisms of HME formation and growth.

John Krall, LCSW

John Krall, LCSW

Responsible for the administrative leadership of the Center for Human Phenomic Science.

Ian D. Krantz, MD

Ian D. Krantz Headshot

Dr. Krantz's lab identifies and characterizes the molecular etiology of syndromic and non-syndromic developmental disorders. He has identified genes for several genetic conditions (Cornelia de Lange Syndrome, CHOPS syndrome, Alagille syndrome, hearing loss) implicating critical molecular pathways in human disorders for the first time. He has been at the forefront of studying the integration of genomics into clinical settings.

Sriram Krishnaswamy, PhD

Sriram Krishnaswamy

Dr. Krishnaswamy studies molecular mechanisms underlying the reactions of blood coagulation. His laboratory investigates how the proteins of blood coagulation interact with each other and with membranes to yield a regulated clotting response to vascular injury or an unregulated response in thrombotic or bleeding disease.

Lauren Krivitzky, PhD, ABPP-CN

Lauren Krivitzky, PhD, ABPP-CN

Dr. Krivitzky's research focuses on cognitive, behavioral, and social outcomes in pediatric stroke and related vascular conditions. She also has an interest in studying outcomes in children and adults with inborn errors of metabolism.
