October 23, 2020
11 a.m. - 12 p.m.
Join the Zoom Session
Dan Rubenstein is a behavioral ecologist who studies how environmental variation and individual differences shape social behavior, social structure, sex roles and the dynamics of populations. He has special interests in all species of wild horses, zebras, and asses, and has done field work on them throughout the world identifying rules governing decision-making, the emergence of complex behavioral patterns and how these understandings influence their management and conservation. In Kenya he also works with pastoral communities to develop and assess impacts of various grazing strategies on rangeland quality, wildlife use and livelihoods. He has also developed a scout program for gathering data on Grevy’s zebras and created curricular modules for local schools to raise awareness about the plight of this endangered species. He engages people as 'Citizen Scientists' and has recently extended his work to measuring the effects of environmental change, including issues pertaining to the global commons and changes wrought by management and by global warming, on behavior. Rubenstein is the Class of 1877 Professor of Zoology. He is currently Director of Princeton's Environmental Studies Program and is former Chair of Princeton University's Department of Ecology and Evolutionary Biology and Director of Princeton’s Program in African Studies. He received his Bachelors degree from the University of Michigan in 1972 and his Ph.D. from Duke University in 1977 before receiving NSF-NATO and King's College Junior Research Fellowships for post-doctoral studies at Cambridge University. As the Eastman Professor, he spent a year in Oxford as a Fellow of Balliol College. He is an elected Fellow of the Animal Behavior Society as well as the American Association for the Advancement of Science, and has received Princeton University's President's Award for Distinguished Teaching. He has just completed his term as president of the Animal Behavior Society and was most recently a Visiting Research Scholar at Merton College, Oxford and a Visiting Fellow at King's College, Cambridge. He just received the Animal Behavior Society's 'Exemplar Award' for a major long-term contribution to animal behavior and Sigma Xi's John P. McGovern Award for Science and Society.​

Epigenetics is the study of phenotypic variation without changes to the underlying DNA sequence. By altering DNA accessibility and higher order chromatin structure through epigenetic modifications, gene expression can be activated or repressed. Chromatin Immunoprecipitation with sequencing (ChIP-seq) is the gold standard for identifying loci associated with a specific target of interest. However, the limitations of ChIP-seq, including large cellular input (106-107 cells), user-to-user variability, and long overall temporal demands (at least 4 days), limit it from being implemented clinically. Adapting ChIP-seq to a droplet microfluidic platform would address these limitations as well as advance its integration into clinical settings. In collaboration with the Mayo Clinic, we are working to streamline ChIP-seq utilizing droplet microfluidics through the development of sequential modules that perform standard steps in the protocol. Our initial module for this system simultaneously lyses whole cells, enzymatically digests chromatin, and delivers antibody-functionalized magnetic beads that target a mark of interest. The second module washes the magnetic beads with the bound target through a co-flow of four distinct wash buffers. Current work focuses on demonstrating the versatility of the droplet integrated ChIP system by incorporating a diverse range of epigenetic marks.​

Camila graduated with a first class with honours in Biochemistry at the University of Westminster. She then embarked on a MRes in Systems and Synthetic Biology at Imperial College London where she applied computational models to predict gene knockouts in E. coli to increase fatty acids production, and validated it experimentally. After completing her degree with distinction, she returned to University of Westminster to pursue her PhD in a multidisciplinary project that combines biochemistry and structural biology, microbiology and medicinal chemistry. Her research focuses on tuberculosis, both developing new inhibitors and understanding how the bacteria becomes tolerant to current antibiotics. During her second year of PhD, she was invited to spend the year working with her collaborators at University of Southern California (USC) in Los Angeles, where she received full training to work in a Biosafety Level 3 facility. Throughout her academic life, she has been actively involved with science communications as she is an event ambassador at the Science Museum London, organizes events for PhD students called PubhD, and recently started communicating science through infographics on her Instagram account.​

Kyle Munson

Postodctoral Researcher
Penn State Chemistry DepartmentUsing Transient Absorption Spectroscopy to Examine the Electronic
Properties of Functional Materials​
October 1, 2020
11 a.m. - 12 p.m.

View the Zoom Session

The growing demand for new technology also increases our need for improved functional materials. Consequently, intense efforts have been made in the scientific community to develop new materials that are capable of being used in a wide variety of applications, such as solar cells, light-emitting diodes (LEDs), and fuel cells. One of the tools used for investigating the properties of functional materials is transient absorption (TA) spectroscopy. This technique is similar to time-lapse photography and enables physical chemists and materials scientists to analyze the properties of materials on “ultrafast” timescales. In this talk, I first give an overview of the basic principles of TA spectroscopy. I then describe several examples in which TA spectroscopy is used to examine the migration of electrons in solar cells and the structural organization of ligands on the surfaces of nanocrystals. Finally, I describe how TA spectroscopy can be used to answer new and exciting questions in the functional material’s research community.

Dr. James Grinias

Analytical Chemistry & Liquid Chromatography at
Princeton University
October 6, 2020
11 a.m. - 12 p.m.
View the Zoom Session
"My research background focuses on the fundamental development of liquid chromatography (LC) columns in capillaries and microfluidic devices. LC columns are at the heart of many analytical separation techniques across pharmaceutical, environmental, and biomedical research projects. Early work focused on the physical structure of the packed chromatographic bed inside a fused silica capillary and led to strategies that could be used to pack more efficient columns in capillaries and also miniaturized microfluidic devices. Other interests have included understanding the physical processes beyond bed structure that impact column performance (included extra-column effects and frictional heating) and applying LC and mass spectrometry (MS) instrumentation to solve analytical problems in neuroscience and molecular physiology.​"
