Members of the Water at Interfaces Group

Jenée Cyran
Postdoctoral Researcher
Phone:+49 (0)6131 379 599

Jenée earned her PhD in the Krummel group at Colorado State University and studied nanoaggregate structural features of polycyclic aromatic hydrocarbons using 2D IR spectroscopy. Here she is studying ice surfaces with SFG.

Sudipta Das
PhD Student
Phone:+49 (0)6131 379 390

Sudipta got his Masters' degree in the Indian Institute of Technology, Kanpur, India, for his work on the calibration of a pulse shaper using an Acousto-Optic Modulator in the group of Prof. D. Goswami. In his PhD he will investigate the water dynamics in charged air-water interfaces using time resolved multidimensional SFG.

Malte Deiseroth

Malte studied physics at the Johannes-Gutenberg University in Mainz. He did his Master in experimental high energy physics, characterizing a prototype for the electromagnetic calorimeter of the PANDA experiment. In his PhD thesis he will investigate the water-air interface using time resolved multidimensional SFG.

Lisa Dreier
PhD Student
Phone:+49 (0)6131 379 778

Lisa studied technical chemistry at Graz University of Technology. In her master thesis she investigated the effect of the introduction of CuInS2 nanoparticles on the efficiency of organic inorganic hybrid solar cells in the group of Prof. Gregor Trimmel. In her PhD project she is studying the influence of flow and potential on interfacial water at solid-water interfaces under the supervision of Prof. Mischa Bonn and Dr. Ellen Backus.

Chunyan Ma
Visiting Postdoctoral Researcher
Phone:+49 (0)6131 379 404

Chunyan earned her PhD in the group of Zhengping Hao at the Research Center for Eco-Environmental Sciences, CAS, where she studied catalytic oxidation elimination of small-molecule air pollutants. Here she is studying the catalytic mechanism of small-molecule gas oxidation with SFG.

Alejandra Sánchez
Doctoral Researcher

Alejandra studied Chemistry and did her Masters in Mavis Montero's group in the University of Costa Rica. Now she has been awarded an MPGC studentship to study ice surfaces.

Jan Schäfer
PhD Student
Phone:+49 (0)6131 379 390

Jan studied Chemistry and received his Master in Spectroscopy and Simulation in the group of Prof. Martina Havenith at Ruhr-University of Bochum. He studied intermolecular interactions of reactive organic species with water using depletion spectroscopy in superfluid He-nanodroplets. For his PhD, he is studying non-equilibrium effects at solid/liquid interfaces using SFG.

Simon Schlegel
PhD Student
Phone:+49 (0)6131 379 269

Simon studied chemistry at the Johannes-Gutenberg University in Mainz. In his diploma thesis at the Max- Planck-Institute for Chemistry he worked with single aerosol particle mass spectrometry in the group of Dr. Johannes Schneider. In his PhD thesis he is investigating the water splitting process on TiO2 surfaces using SFG.
