Dr. Iffland is an Assistant Professor in the Department of Neurology at the University of Maryland School of Medicine. His research involves using in vivo and in vitro methods to functionally validate and define the pathophysiological consequence of mutations associated with cortical malformations and epilepsy. Diseases studied in the Iffland lab include Focal Cortical Dypslasia, Tuberous Sclerosis Complex, Hemimegalencephaly, and Megalencephaly.

Dr. Iffland is particularly interested in mutations in the amino acid regulatory arm of the mTOR pathway (e.g., DEPDC5 and NPRL3; "GATORopathies") and how they impact neuronal morphology, function, and brain development. In additon he has interest in the changes in protein expression that occur as a result of mTOR pathway hyperactivation and how those changes contribute to cortical lesion formation and epileptogenesis with the ultimate aim of discovering novel targets for treatment.

The Iffland lab uses both in vivo and in vitro approaches to model various aspects of cortical malformations associated with mTOR pathway variants. These include live-cell imaginng, multi-well multielectrode array, in utero electroporation, long-term vido-EEG recording in rodents, morphometry, and cell signaling assays.
