7 Division of Science Faculty Recently Promoted

Congratulations to the following 7 Division of Science faculty members were recently promoted:

katz_dbDonald B. Katz (Psychology) has been promoted to Professor of Psychology. Don came to Brandeis as an Assistant Professor with a joint appointment in the Volen Center for Complex Systems in 2002 and was promoted to Associate Professor and awarded tenure in 2008. Don’s teaching and research serve central roles in both Psychology and the Neuroscience program. His systems approach to investigating gustation blends behavioral testing of awake rodents with multi-neuronal recording and pharmacological, optogenetic, and modelling techniques. Broad themes of the neural dynamics of perceptual coding, learning, social learning, decision making, and insight run through his work on gustation. For his research, Don has won the 2007 Polak Award and the 2004 Ajinomoto Young Investigator in Gustation Award, both from the Association for Chemoreception Sciences. Don has taught “Introduction to Behavioral Neuroscience” (NPSY11b), “Advanced Topics in Behavioral Neuroscience” (NPSY197a), “Neuroscience Proseminar” (NBIO250a), “Proseminar in Brain, Body, and Behavior II” (PSYC302a), “How Do We Know What We Know?” (SYS1c). For his excellence in teaching, Don has been recognized with the 2013 Jeanette Lerman-Neubauer ’69 and Joseph Neubauer Prize for Excellence in Teaching and Mentoring, the 2006 Brandeis Student Union Teaching Award, and the 2006 Michael L. Walzer Award for Teaching and Scholarship.

Nicolas RohlederNicolas Rohleder (Psychology) has been promoted to Associate Professor in Psychology. Nic is a member of the Volen Center for Complex Systems and on the faculty of the Neuroscience and Health, Science, Society and Policy programs. His course offerings include “Health Psychology” (PSYC38a), “Stress, Physiology and Health” (NPSY141a), and” Research Methods and Laboratory in Psychology” (PSYC52a). Nic’s research investigates how acute and chronic or repeated stress experiences affect human health across individuals and age groups. His laboratory performs studies with human participants using methods than span behavioral to molecular to understand how the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) regulate peripheral immunological responses and how these processes mediate cardiovascular disease, type 2 diabetes, and cancer, and aging. His research and teaching fill unique niches for all his Brandeis departmental and program affiliations. Nic’s research excellence has been recognized outside Brandeis with awards including the 2013 Herbert Weiner Early Career Award of the American Psychosomatic Society and the 2011 Curt P. Richter Award of the International Society of Psychoneuroendocrinology.

Matthew HeadrickMatthew Headrick (Physics) has been promoted to Associate Professor of Physics. He works at the intersection of three areas of modern theoretical physics: quantum field theory, general relativity, and quantum information theory. In particular, he uses information-theoretic techniques to study the structure of entanglement — a fundamental and ubiquitous property of quantum systems — in various kinds of field theories. Much of his work is devoted to the study of so-called “holographic” field theories, which are equivalent, in a subtle and still mysterious way, to theories of gravity in higher-dimensional spacetimes. Holographic theories have revealed a deep connection between entanglement and spacetime geometry, and Headrick has made significant contributions to the elucidation of this connection. Understanding the role of entanglement in holographic theories, and in quantum gravity more generally, may eventually lead to an understanding of the microscopic origin of space and time themselves.

Isaac Krauss

Isaac Krauss (Chemistry) has been promoted to Associate Professor of Chemistry. He is an organic chemist and chemical biologist whose research is at the interface of carbohydrate chemistry and biology. His lab has devised tools for directed evolution of modified DNA and peptides as an approach to designing carbohydrate vaccines against HIV. Krauss is also a very popular teacher and the recipient of the 2015 Walzer prize in teaching for tenure-track faculty.

Xiaodong Liu (Psychology) has been promoted to Associate Professor in Psychology. Xiaodong provides statistical training for graduate students in Psychology, Heller School, IBS, Neuroscience, Biology, and Computer Science, he serves as a statistical consultant for Xiaodong LiuPsychology faculty and student projects, and he performs research on general & generalized linear modeling and longitudinal data analysis, which he applies to child development, including psychological adjustment and school performance. He teaches “Advanced Psychological Statistics I and II” (PSYC210a,b), “SAS Applications” (PSYC140a), “Multivariate Statistics I: Applied Structural Equation Modeling” (PSYC215a), and “Multivariate Statistics II: Applied Hierarchical Linear Models” (PSYC216a). He is developing a new course on “The R Statistical Package and Applied Bayes Analysis”, and he recently won a Provost’s Innovations in Teaching Grant for “Incorporating Project-based modules in Learning and Teaching of Applied Statistics”.

Gabriella SciollaGabriella Sciolla (Physics) has been promoted to Professor of Physics. She is a particle physicist working on the ATLAS experiment at CERN in Geneva, Switzerland. Sciolla and her group study the properties of the newly discovered Higgs Boson and search for Dark Matter particles produced in high-energy proton-proton collisions at the Large Hadron Collider. Sciolla is also responsible for the reconstruction and calibration of the muons produced in ATLAS. These particles are key to both Higgs studies and searches for New Physics.

Men, Women and Emotional Stress Responses

Psychoneuroendocrinology (November 2014) is publishing a fascinating paper authored by Sarah Lupis, Michelle Lerman and Jutta Wolf titled Anger responses to psychosocial stress predict heart rate and cortisol stress responses in men but not women.

473People can experience a wide range of emotions when under stress, including feelings of anger and fear. In recent years researchers have sought to understand how these emotion stress responses are linked to biological stress responses. In particular, some evidence suggests that anger and fear may be linked to cardiovascular changes in differential ways. It is less clear, however, how emotions during stress may predict increases in levels of the stress hormone cortisol. These deficits in our understanding are partly due to the methodological difficulties in measuring emotion in the context of stress. Much prior research has relied solely on retrospective self-report (after the stress has passed, a questionnaire asks a study participant to reflect on how he felt in the moment of stress). By this time, the participant may have forgotten how he felt, or may already be utilizing coping strategies to process those emotions. In addition, he may not feel comfortable reporting how the stressor made him feel, leading to less-than-honest responses. Unsurprisingly, prior research has not shown consistent links between these self-report measures and biological stress responses. In the current study, we therefore added facial coding of emotion expression to assess emotions occurring during stress. Our aim was to determine how expressions of anger and fear were linked to heart rate and cortisol stress responses.

We recruited 32 healthy Brandeis students and exposed them to a brief psychosocial stressor. A certified coder assessed facial expressions shown during the stressful situation. Heart rate and cortisol levels were measured throughout. After the stressor, the participants also self-reported how they felt during the stressor. A first notable finding showed that what participants self-reported feeling and the expressions they actually showed did not correlate. With regards to self-report, men who reported feeling fear showed blunted cortisol stress responses. Consistent with prior research, self-report was otherwise not associated with heart rate or cortisol stress responses. When looking at facial expressions, a consistent pattern appeared: men who showed more anger during the stressful situation also showed exaggerated heart rate and cortisol stress responses. For women, neither anger nor fear were linked to biological stress responses (see Figure).

Our findings first emphasize the importance of assessing emotion using multiple means. In this case, facial expressions revealed an emotion-stress link for males that would not be apparent using self-report alone. Facial coding may thus be a useful addition to current stress paradigms. Further, if men who react with anger in stressful situations do respond with exaggerated stress responses, it could have important down-stream health effects. Exaggerated, prolonged, or dysfunctional stress responses could, over time, lead to changes in basal stress systems. This kind of ‘allostatic load’ is associated with negative health outcomes including diabetes and cardiovascular disease. Anger and fear do not seem to drive these responses in females, and further study is needed to determine if similar relationships exist for a different set of emotions, perhaps self-conscious emotions like shame. By better understanding these relationships, more healthful ways of coping with stress can be developed, which is particularly important given that for many, stress has become an unavoidable part of daily life.

 

Art Wingfield Festschrift – “Age, Hearing, and Speech Comprehension”

Brandeis_072214_004b

On July 22nd, 70 colleagues, friends, and students gathered for a festschrift in honor of Art Wingfield, the Nancy Lurie Marks Professor of Neuroscience. The theme of the day was Age, Hearing, and Speech Comprehension, reflecting Art’s research interests.

Brandeis_072214_064In addition to a scientific program composed of talks centered on this topic, the day also featured former students, collaborators, and colleagues sharing stories about Art. These included Stefanie Kuchinsky (2003) who completed a senior honors project in Art’s lab, former postdoc Marianne Fallon, former students Cindy Lahar and Sarah Wayland, and colleagues from the Department of Psychology (Jim Lackner and Paul Dizio).

The day ended with the surprise announcement of the establishment of an annual travel award in Art’s name that will support a graduate student in psychology or neuroscience to travel to a scientific conference, and dinner in town. A great time was had by all!
