Ed O'Brien, Assistant Professor of Chemistry, has been selected to receive a National Science Foundation Faculty Early Career Development (CAREER) award. CAREER is a Foundation-wide activity that "offers the National Science Foundation's most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations."
Research in the O'Brien addresses fundamental questions regarding molecular and cellular processes in chemistry and biology.
Scott Phillips, an associate professor of chemistry at Penn State University and holder of the Lou Martarano Career Development Professorship, has been honored with the inaugural Stephen and Patricia Benkovic Early Career Professorship. Stephen J. Benkovic, an Evan Pugh Professor of Chemistry and Holder of the Eberly Family Chair in Chemistry at Penn State University, and Patricia Benkovic, a research associate in chemistry at Penn State, established the professorship to support outstanding early career faculty in the Penn State Eberly College of Science. The professorship offers early recognition for outstanding accomplishments and provides financial support to promising young faculty members to encourage establishing a commitment to teaching and explore new areas of research.
Phillips focuses his research on organic and environmental chemistry, the design and synthesis of molecules with unique functions, analytical and bioanalytical chemistry, and materials chemistry. In one project, Phillips is developing materials that respond to external signals by changing shape, function, and/or surface properties. Phillips also is working on a project in which he uses organic chemistry to create diagnostic devices that provide all the functions typically obtained with laboratory instruments, but that use only organic reactions. These systems may be useful in applications that require portable and inexpensive devices for detecting disease or pollution; for example, in the developing world and in hospital emergency rooms. A second program in this area focuses on reaction networks that are self-perpetuating, the simplest of which is an autocatalytic reaction, in which a molecule makes more of itself. Phillips plans to expand autocatalytic behavior into more complex reaction networks, with a goal of developing systems that provide useful functions and byproducts.
Phillips's previous awards include being named an Emerging Investigator by the journals Analytical Methods and Polymer Chemistry in 2015, and the journal Chemical Communications in 2014. He was awarded the Arthur F. Findeis Award for Achievement by a Young Analytical Scientist in 2015, the Eli Lilly and Company Young Investigator Award in Analytical Chemistry in 2013, an Alfred P. Sloan Research Fellowship in 2012, and a Faculty Early Career Development (CAREER) award from the National Science Foundation (NSF), also in 2012. He was honored with three 3M Non-Tenured Faculty Awards in 2010, 2011, and 2012, and he received a Defense Advanced Research Projects Agency (DARPA) Young Faculty Award from the United States Department of Defense in 2010. In that same year, he won an Outstanding Professor in Chemistry award from the honor society Alpha Chi Sigma. In 2009, Phillips won a Popular Mechanics Breakthrough Award and a research award from the Bill and Melinda Gates Foundation. In that same year, he also won a Beckman Young Investigator Award, a Thieme Chemistry Journal Award, and a Penn State Eberly College of Science Dean's Climate and Diversity Award. In 2008, he won a New Faculty Award from The Camille and Henry Dreyfus Foundation.
Prior to joining the Penn State faculty in 2008, Phillips worked from 2004 to 2008 as a postdoctoral fellow at Harvard University, where he developed new materials and detection platforms for use in drug development. He also synthesized chemical compounds with anticancer properties from marine organisms. Phillips earned a doctoral degree in chemistry at the University of California at Berkeley in 2004. He earned a bachelor's degree in chemistry at the California State University in San Bernardino in 1999.

Ray Schaak has been selected as the 2016 winner of the ACS Inorganic Nanoscience Award. The award is given annually to one chemist under the age of 45. The award recognizes sustained excellence, dedication, and perseverance in research and service in the area of inorganic nanoscience.
For the first time, scientists have demonstrated a simple charge-based mechanism for regulating the formation and dissolution of liquid-like structures that lack outer membranes inside cells. The research provides a first step in deciphering how these poorly-understood structures function in the cell and how they may have evolved. The research, conducted by Penn State University scientists, will appear December 21, 2015, as an advance online publication of the journal, Nature Chemistry.
"Cells contain many of these liquid-like structures that are in some ways conceptually similar to droplets of oil in water," said Christine Keating, professor of chemistry at Penn State University. "The structures, which we call liquid organelles, often appear and disappear inside cells. We were able to replicate this process in a biologically-reasonable way in the lab by controlling the electrostatic charge of the molecules that form our synthetic liquid organelles. We used tools that the cell itself might use, giving us the first clues about how the process may occur in nature."
"The assumption is that these liquid organelles compartmentalize molecules like RNAs and proteins in order to speed up reactions inside cells," said William Aumiller, a graduate student at Penn State at the time the research was conducted. "This field is very new and there are likely many different mechanisms by which liquid organelles form in cells, so exploring fundamental questions like 'what are the minimum requirements to make these structures come and go as they do in the cell' is very important."
The researchers created synthetic liquid organelles by combining, in a solution, negatively charged RNA molecules with positively-charged short peptides -- chains of amino acids similar to, but smaller than, proteins. Because the two molecules have opposite charges, the News Christine Keating 12-2015 page 2 of 2
RNAs and peptides are attracted to one another and self-assemble into droplets that simulate liquid organelles.
The researchers then adjusted the charge of the peptide molecules in the synthetic liquid organelles by using common enzymes -- proteins that catalyze specific reactions in a cell. They used one type of enzyme, called a kinase, to add phosphate groups -- negatively-charged chemical components -- to the peptides to neutralize their positive charge. Neutralizing the peptides in this manner caused the synthetic liquid organelles to break apart. The scientists then reversed this process and the synthetic liquid organelles reformed by adding another type of enzyme, called a phosphatase, which removed the phosphate group from the peptides, reestablishing their positive charge.
"All sorts of reactions in cells are controlled by modifying proteins with kinases and phosphatases," said Keating. "As chemists, we were thinking about the most basic mechanisms that could be involved in the formation of these liquid organelles, and it's reasonable to think that this is one mechanism that cells might use. Now, we can use our new system to study these liquid-like structures and how they may have evolved."
The research was supported by the National Science Foundation (grant MCB-1244180).

Booker will receive flexible support designed to enable him to move his research forward in creative new directions.
Booker’s main research interests include deciphering the molecular details by which enzymes -- a special class of proteins -- catalyze reactions in the cell. He then uses the insight gained to manipulate these reactions for various objectives, ranging from the production of biofuels to the development of antibacterial agents. His laboratory garnered international attention for elucidating a pathway by which disease-causing bacteria such as methicillin-resistant Staphylococcus aureusevade entire classes of commonly used antibiotics. These results were published in two papers in the journal Science, a paper in Nature Chemical Biology, and two papers in the Journal of the American Chemical Society. He is particularly well known for his research on enzymes employing extremely reactive molecules, known as free radicals, to catalyze their reactions.
In 2014, Booker was been named a Fellow of the American Association for the Advancement of Science (AAAS), the world's largest general scientific society and the publisher of the journal Science. In 2011, Booker was honored with an Arthur C. Cope Scholar Award. The award, which consists of a monetary prize and an unrestricted research grant, is given by the American Chemical Society "to recognize and encourage excellence in organic chemistry." In 2004, Booker was recognized as one of 57 of the country's most promising scientists and engineers by President George W. Bush with the Presidential Early Career Award for Scientists and Engineers. He received the award at the White House in recognition of his research on enzyme reactions, including his work on an enzyme involved in the synthesis of unusual fatty acids, which is needed by the bacteria responsible for most cases of tuberculosis. In 2002, he received a National Science Foundation Faculty Early Career Development (CAREER) award, the agency's most prestigious award for new faculty members.
Booker has mentored 15 graduate students, over 35 undergraduate students, and two high-school students. He is known for encouraging students in underrepresented groups to consider science-based careers. Booker has published about 70 scientific papers in journals such as Science, the Journal of the American Chemical Society, and Proceedings of the National Academy of Sciences, and he has served as guest editor for Current Opinion in Chemical Biology, Biochimica Biophysica Acta, and the Journal of Biological Chemistry. He is past-chair of the Minority Affairs Committee of the American Association of Biochemistry and Molecular Biology, and is co-organizer of the society's 2016 annual meeting.
Booker earned a bachelor's degree in chemistry at Austin College in 1987, where he was a Minnie Stevens Piper Scholar, and a doctoral degree in biochemistry at the Massachusetts Institute of Technology in 1994. That same year he was awarded a National Science Foundation–NATO Fellowship for postdoctoral studies at Université Rene Décartes in Paris, France. Later, in 1996, he was awarded a National Institutes of Health Postdoctoral Fellowship for studies at the Institute for Enzyme Research at the University of Wisconsin. He joined the Penn State faculty in 1999.
