Dr. George Siopsis, Director of GSSE

George SiopsisGeorge Siopsis is a professor in the Department of Physics and Astronomy at the University of Tennessee. He grew up in Greece and attended Sussex University in England where he got his B.Sc. degree majoring in mathematical physics. He did his graduate work at Caltech studying theoretical elementary particle physics, receiving his PhD in 1987. He then spent a few years as a research associate at Texas A&M University working on string theory before moving to Tennessee in 1991.

In recent years, his research has focused on quantum gravity and related issues (holography, entanglement, black holes and the information loss paradox), and applications to condensed matter physics. He has trained several PhD students who have embarked on promising careers, and introduced undergraduates as well as high school students to research in quantum physics and fundamental interactions. Currently, he is working on quantum computing and quantum information processing in collaboration with members of the Quantum Information Science group at Oak Ridge National Laboratory.

Dr. Stephanie Drumheller-Horton, Course Director (Biology)

My research interests center on vertebrate taphonomy, ichnology, paleopathology, and paleoecology. In particular, I study bone surface modifications generated under modern and experimental conditions to better understand the processes which left similar traces on bone in the fossil record. My current research projects include:

  1. testing methods for applying these modern analogies in a deep time perspective
  2. interpreting trophic interactions, behavior, and diet from bite marks left by different archosaurian groups, especially members of Crocodyliformes
  3. identifying and differentiating historically understudied traces and pathologies, such as bite marks vs. shell disease and different types of plant mediated damage to bone.

Bhavya Sharma, Course Director (Chemistry)

Bhavya Sharma received her PhD degree in Chemistry from the University of Pittsburgh in 2011. Following a postdoctoral research position, she started her academic career at the University of Tennessee in August 2015. Bhavya’s research involves the use of Raman spectroscopy, a light scattering technique, to examine the underlying physics and chemistry of biological systems. In particular, her group is interested in biomedical applications of Raman spectroscopy. Dr. Sharma’s group also uses nanoscience in their development of biochemical assays for biomarkers of human health.


Dr. Remus Nicoara, Course Director (Mathematics)

Remus NicoaraDr. Remus Nicoara earned his Ph.D. in Mathematics from UCLA, and his Bachelor’s Degree from the University of Bucharest, Romania. He is currently a Professor of Mathematics and Director of the Math Honors Program at the University of Tennessee. His main research interest lies in von Neumann algebras, which are algebras of operators that model quantum mechanical systems. Outside of work, Remus likes to hike, bike and garden while thinking about math. He enjoys meditation, Sci-Fi books, and Hanayama puzzles. He is also an avid gamer and he currently teaches a class about video games and math, called Math Effect.


Dr. Haidong Zhou, Course Director (Physics)

Haidong ZhouHaidong Zhou is an associate professor in the Department of Physics and Astronomy at UTK. Haidong obtained his PH.D. in Physics in December 2005 from University of Texas at Austin. He became a Postdoctoral Associate at National High Magnetic Field Lab/Florida Sate University with Prof. C. R. Wiebe. In August 2008, he obtained a position as assistant scholar/scientist in NHMFL. He became an Assistant Professor in the Physics Department at UTK in August 2012.

Haidong’s research is concerned with the nature of phase transitions in condensed matter systems, especially strongly correlated systems and quantum matters. More specifically, he is involved with the single crystal growth and using the x-ray scattering, low temperature and high magnetic field measurements, and neutron scattering, as complementary probes to study the spin, electron and structure of solids. His research interests are:

  • Single crystal growth
  • Geometrically frustrated magnets (GFM)
  • Multiferroic systems
  • Systems with strong spin/orbital/lattice coupling
  • Systems approaching the itinerant electron limit
