Samuel I. Merenbloom, Ph.D.

Postdoctoral Researcher (NIH F32 Fellow). B.S. (magna cum laude),University of Maryland, Baltimore County (2004). Ph.D., Indiana University (2009). Interested in instrumentation, with a focus on ion mobility spectrometry-mass spectrometry. Also interested in the conformations adopted by proteins and macromolecular complexes in the gas phase, and the role conformation plays on other gas phase phenomena. Has been accused (though never convicted) of being fun, does not particularly like sand.

Jeremy T. O'Brien

Graduate student researcher.  B.S. Washington University (2004). Likes long walks on the beach and having fun.

Tawnya G. Flick

Graduate student researcher. B.S., B.A., University of California, Santa Barbara (2004). My research is focused on the development and application of new methods in mass spectrometry to solve key challenges related to biological molecules. Recently, we have developed a new method to quantify components in complex mixtures without the use of standards. This method has been applied to the quantification of small molecules in pharmaceutical tablets and peptides in mixtures. My research is also focused on the development of techniques to study the physical properties of biological molecules in the gas phase, whether in isolation or in a larger complex, and how these properties contribute to other gas phase observables.

Maria Demireva

Graduate student researcher. B.S. Distinction and Honors, University of North Carolina - Chapel Hill (2007). I am interested in ion solvation and its effect on ion structure. I use both experimental techniques, such as ion nanocalorimetry, and theoretical calculations, such as RRKM and master equation modeling. With these methods I investigate the thermodynamics, dissociation kinetics, and energy transfer processes of various hydrated ions when activated via collisions with neutrals, electron capture, or absorption of photons.

Terrence M. Chang (Terry)

Graduate Student Researcher B.S., Emory University (2009). My research interests include ions, spectroscopy, ion spectroscopy, and video games. I also have an interest in teaching, especially at the undergraduate level.

Catherine A. Cassou

Graduate student researcher. B.S. (summa cum laude) University of Notre Dame (2010). I am studying mass spectrometry techniques with applications to structural biology of large proteins and protein complexes. My research thus far has concerned demonstrating, through protein crosslinking and hydrogen-deuterium exchange experiments, that protein supercharging in electrospray ionization occurs via chemical and/or thermal denaturation. I am also currently involved in a collaboration with the Krantz Group to use mass spectrometry to study conformational changes in Anthrax toxin.

Richard J. Cooper

Graduate Student Researcher. B.S. (summa cum laude) Boston College (2011). My research focuses on the study of non-covalent interactions in gas phase ion-molecule complexes. I use infrared multiple photon dissociation (IRMPD) spectroscopy along with computational theory to elucidate the structure, energetics and reactivity of m/z-selected complexes. Applications include ion-biomolecule structures, the effect of ions on protein stability and a means of gathering novel thermodynamic data.

Daniel Mortensen

I barely graduated from Brigham Young University in 2011 with a B.S. in chemistry where I studied inclusion complexes of pumpkin shaped cage molecules in the gas phase. I'm currently studying the lifetime of an electrospray droplet to further the understanding of the mechanism for electrospray ionization. I'm a cancer. And I won that pie eating contest.
