Biography
Focus of our current research is the investigation of mechanisms involved in nitrogen excretion and acid-base regulation in invertebrate systems that includes crustaceans, insects, cephalopods, chelicerate, planarians and annelids. In a comparative approach we are also examining the effects of challenges that come due to anthropogenic caused increases in atmospheric PCO2 levels on the physiology of aquatic animals inhabiting fresh and seawater. In addition, using rodent systems and human carcinoma cell lines (T84 and Caco-2) the nitrogen transport mechanism are investigated in the mammalian intestine. For all our study an integrative approach is applied.
Research Interest
Nitrogen transport in the mammalian intestine, Physiology, Integrative and comparative physiology of transepithelial transport, Ammonia transport in changing environmental salinities, Physiological and molecular approaches.
