2010 Faculty Promotions

We are very pleased to announce the promotion of several of our faculty. As you can see from the descriptions below, they all lead exciting research programs. In addition, they all uniquely contribute to the high quality educational experience of our undergraduate and graduate students.

 Miriam Bassok: promotion to Full Professor

She is interested in understanding how one’s semantic understanding of real world objects impacts our approach to solving problems.  She was the first to find that our reasoning abilities (especially in the domains of physics and math) appear to be dramatically influenced by our (learned) understanding of the functions and significance of the elements of the problem.  For example, people tend to add together objects that are perceived to come from the same semantic category: tulips and roses (from the semantic category of flowers) tend to be added together. In contrast objects from different semantic categories (e.g. tulips and vases) tend to divide object numbers. Dr. Bassok’s most recent work shows that the impact of this kind of semantic alignment occurs without the awareness of the individual. This knowledge about our reasoning abilities could have profound implications for the development of math or physics related curricula at all levels (K-12, or even college level). Most recently, Dr. Bassok has established a new collaboration with Professor Osterhout in our department to begin neurobiological assessment of semantic alignment and its consequences.

 Ione Fine: promotion to Associate Professor with tenure

Cheryl Kaiser: promotion to Associate Professor with tenure

Her research describes the negative social stigma attached to individuals that blame racial discrimination for their negative evaluation. This can explain why few workers are willing to complain when they feel discriminated against. Another facet of her work studies how the social perception of an individual that belongs to a stigmatized group can vary depending on how much that individual identifies with the stigmatized group. NSF funded work focuses on the conditions that lead to a group member deciding whether to interfere or help with the success of another group member in a highly competitive situation. For example, will senior female colleagues interfere with the promotions of junior female colleagues? The question is: will those higher up on the ladder ‘lift up’ or ‘kick down’ colleagues from a similar stigmatized group?  Dr. Kaiser’s work has already impacted national policy, and has the potential to have direct impact at state and local levels as well. 

Scott Murray: promotion to Associate Professor with tenure

This is a great example of how contextual information affects the way information is represented in the brain.  Importantly, receptive fields of V1 neurons, which had previously been considered static, dynamically shift depending on the perceived distance of an object. This may have important implications for further neural processing in the service of learning and memory.

Sean O’Donnell: promotion to Full Professor

His research seeks to understand the neurobiological and evolutionary (i.e. genetic) basis of social behaviors of all animals. To study such a complex problem, Dr. O’Donnell developed methods for studying model animal systems that have clear social organization (and hence are tractable).  These are societies of wasps, bees, and ants. Within these groups he studies fascinating topics such as the determinants of social hierarchies, socially-induced aggression, and communication amongst members of a society.  He looks not only at adult systems, but he is also interested in how these complex behaviors develop and change within a lifetime. In addition to this core research program, Dr. O’Donnell has become interested in understanding the impact of human habitats and climate change on the variety of terrestrial ecosystems in the tropical montane forests.

Joe Sisneros: promotion to Associate Professor with tenure
