Students currently collaborating in my lab:

Yolana
Yolana Fuks is a junior and works with the midgut of adult yellow fever mosquitoes (Aedes aegypti). In the moment, the major aim is to mount posterior midguts on perfusion pipettes, measure the transepithelial voltage as an indicator for active and electrogenic transport, and activate the transport capacities with hormonal and non-hormonal factors.
Yolana is a Biology major with a minor in Chemistry. She was accepted for a summer research internship at Johns Hopkins University.
Sejmir
Sejmir Izeirovski is a senior and studies the influence of nutrients on the transepithelial voltage and strong alkalinization of the anterior midgut of larval yellow fever mosquitoes (Aedes aegypti). Sejmir and I produced a number of abstracts/presentations, and he is a coauthor on one article (see Publications ). Sejmir also got an article accepted for publication in the Wagner College Bulletin for Undergraduate Research, and an updated and modified version of this article was just submitted to the Journal of Experimental Zoology. Sejmir plans to go to medical school.
Melanie2
Melanie Valencia is a freshman and just started to collaborate in the mosquito project.

Alumni at Wagner College:

Margarita
Margarita Javoroncov collaborated in spring 2007 with the biochemical measurements for our publication in the Journal of Experimental Zoology (see Publications). Margarita graduated in 2007. She is currently working at Musculoskeletal Transplant Foundation (MTF) and the New Jersey Sharing Network. For fall '09, Margarita has been accepted into the MD program of the Medical College of Wisconsin.
Malay
Malay Patel contributed observations with living larval yellow fever mosquitoes to our publication in the Journal of Experimental Zoology (see Publications). Malay is currently at a medical school in the Carribean. He is graduating this spring and, after taking the USMLE (Step 1), is planning to do the clinical part of his education in a hospital in the US.
Alfred
Alfred Phillips observed alkalinization in living larval yellow fever mosquitoes at different larval stages. Alfred graduated in 2008.


Alumni from my labs in Germany and Brazil:

Antonio
Antonio Hernandez Torres Jr. collaborated with me during the experimental work for his PhD thesis in Brazil. Antonio studied ion transport across the gills and antennal glands of freshwater crustacea. Together with me, Antonio analyzed the transepithelial voltage of isolated and perfused gills of the freshwater prawn Macrobrachium rosenbergii.
Andy
Andreas Schöbel and Jan Kraft collaborated with me in the frame of their MSc thesis at the Free University of Berlin, Germany. Both studied aspects of the hormonal regulation of active NaCl absorption across the gills of Chinese crabs (Eriocheir sinensis; see Publications ). Andreas is currently working at EWE NaturWatt, a company producing and marketing wind energy in Northwestern Germany.
Mohammad
Mohammad Ranagad worked in my lab at the Free University of Berlin, producing data for his MSc thesis about the pH dependence of NaCl absorption across the gills of Chinese crabs (Eriocheir sinensis). After some years in the Artemia Research Center in Uromieh (Iran), Mohammad is now in Hannover, Lower Saxony (Germany).
Dietmar
Dietmar Kültz collaborated with me in Berlin on aspects of ion transport across the opercular epithelium of fish in the frame of his PhD thesis at the University of Rostock, Germany (see Publications). Dietmar is now Associate Professor for Physiological Genomics at the University of California, Davis. Dietmar has a very interesting webpage. For a visit click here!
Sven
Sven Riestenpatt collected the results for his MSc thesis in my lab at the Free University of Berlin. Sven studied the influence of theophylline and db-cAMP on NaCl absorption across Chinese crab gills. Sven and I continued to collaborate while he was working on his PhD in the lab of Dieter Siebers at the Biologische Anstalt Helgoland in Hamburg. Sven and I published a number of papers together (see Publications). Sven is now an assistant editor at the scientific publisher Karger.
