In the human body, the liver is the only organ that can regenerate following substantial damage. But if all cells contain the same genetic information, how is this function unique to the liver? This summer I will study regeneration in the wing imaginal discs of developing Drosophila larvae. My goal is to develop a system that introduces localized cell death in these discs. Following cell death, I will visualize the amount and location of cell proliferation in the remaining cells. With this system, I can assess the ability of mutant […]

There are forms of the gecko species, Heteronotia binoei, that reproduce sexually that gave rise to forms that reproduce asexually through the process of parthenogenesis. Parthenogens have sections of duplicated genes in their mitochondrial genome while sexual forms do not. My project is to sequence and compare the mitochondrial genes of the sexual and parthenogenic forms to characterize their evolution since their divergence. I will also compare duplicated gene copies to one another within the parthenogenic individuals to characterize evolution of each gene since the duplication event. Gene duplication and […]

My research will focus on the effects of stress on neurogenesis (the birth of new neurons) in the dentate gyrus (DG) of the adult rat hippocampus. The hippocampus is essential for memory and learning function. Interestingly, chronic stress has been shown to decrease cell proliferation in the DG and reduce the effectiveness of hippocampuss memory function. My project will investigate one potential factor that may prevent stress-induced reduction of neurogenesis: controllability. Studies have shown that animals that can control the onset/offset of stress do not show many negative effects of […]

This summer I will be working in ion trap quantum computing. Quantum computing is an alternate form of computation that uses a quantum bit, called a “qubit”, in place of the binary system. My professor, Hartmut Haeffner, isolates ions in radio frequency traps to create qubits. This trapping must take place in an ultra high vacuum so that air molecules do not interfere with the ion. My project entails building RC filters for the ion trap that are compatible with the vacuum. These filters need to remove any radio frequency […]

I am interested in the thermal ecology of two tropical skinks, Emoia cyanura and E. impar, in Tahiti, French Polynesia. Since these skinks are so similar in morphology and ecology, they likely compete for essential resources, including sources of heat. So far, through field observations and lab experiments, I have found that E. cyanura prefers open canopy habitats and warmer body temperature relative to E. impar. To expand my study, I will test sprint speed of each species at different body temperatures to see if they are thermal “generalists” or […]

A detailed mechanism of this so-called “feature detection” has been recently studied in humans; however, this mechanism has not been investigated in any animal model yet (Neri and Heeger 2002). Due to the general belief that rodents have very poor vision, scientists have paid little attention to them on the topic of visual perception. However, studies in the last 10 years have actually shown that the rodent visual systems present properties similar to those of other mammals such as cats and monkeys. Therefore, I believe rodents could be used as […]

9-cis-retinoic acid (9cRA) is one of the many derivatives of vitamin A. Although vitamin A derivatives are most known for their involvement in sight, they are involved in many physiological process such as the immune response, the development of many organs, and the maintenance of normal internal conditions like blood glucose. Normally, glucose levels are closely regulated by hormones of the pancreas such as insulin and glucagons. However in the case of diabetes, this tight regulation collapses. 9cRA has shown potential in correcting the hormonal imbalance characteristic of diabetes. How […]

My experiment examines two possible models of how the brain determines which arm to use during reaching movements. Under the non-competitive model, the motor areas in each hemisphere formulate a plan and race until one has reached some threshold level of activation for movement, while the competitive model has the two hemispheres race while sending inhibitory signals to each other. I’ll be giving subjects a simple reaching task in which they must respond to cues on a screen, but occasionally withhold their movement in response to a later stop cue. […]
