This research project will investigate the effects of redox conditions on temperature sensitivity of soil methane (CH4) and carbon dioxide (CO2) respiration. Temperature and rainfall regimes are changing with climate change, which can create fluctuating redox dynamics in humid environments such as tropical forests and wetlands. This has global implications for ecosystem carbon (C) storage and loss. CH4 is a potent greenhouse gas produced under anaerobic conditions, and the effects of changes in temperature on redox and CH4 fluxes are not well understood. Fe-reducing microorganisms can contribute significantly to CO2 […]

Listeria monocytogenes is a Gram-positive pathogenic bacterium that causes the foodborne illness Listeriosis in humans. The Portnoy lab discovered that L. monocytogenes has the ability to do extracellular electron transfer (EET), which consists of transferring electrons from the inside of the bacteria to extracellular acceptors outside, using compounds called flavins. This process allows L. monocytogenes to grow on non-fermentable carbon sources, and strains lacking EET activity have been shown to have reduced viability in vivo. I will be studying the role of two proteins discovered to be essential for EET […]

Largely understudied, small-scale fisheries are critical to coastal livelihoods in the global south, yet are poorly represented in conversations about development, food security, human rights, and gender equity. The creation of marine-protected areas and parks along coastal regions with marine biodiversity in mind has displaced the livelihoods of traditional fishers. I will be investigating reactions and adjustments to this displacement along the caribbean coast of Colombia.

Circadian rhythms are daily rhythms generated by all mammalian tissues that are critical to numerous physiological functions. These rhythms have far-reaching influence on the brain and periphery; therefore, circadian regulation of hormones is essential for normal functioning, and disruptions to circadian timing (e.g. irregular sleep patterns, nighttime light exposure, etc.) have detrimental health consequences. Labor and birth are reproductive events that exhibit a circadian rhythm by which human labor and birth tend to cluster during nighttime. Melatonin is a hormone secreted at night that is inhibited by light. We theorize […]

Western political scientists and multilateral development banks (MDBs) are speculating about the extent to which Chinese development finance (CDF), specifically via the Belt and Road Initiative (BRI) may support or challenge the Western-led global economic order. To determine the extent to which Chinese-led projects may conflict with Western liberal policy agendas and the global economic status quo, as well as whether or not BRI actions may create a debt trap for borrowers, we need more data on how the Chinese conduct development infrastructure projects on the ground, and how they […]

If you turn on the television, chances are high that the news will be painted with violent criminals, Cops will be on all night, and Law and Order will be playing steady reruns. There is a plethora of scholarship investigating the ways media sensationalizes crime and portrays prison in a violent light; however, there exists a gap in research into understanding the ways in which people digest and make of use these images. People, whether they are affected by the criminal justice system or not, view fictitious media depictions that, […]

The Grove has become one of Los Angeless main attractions, housing a farmers market, an assortment of shops, entertainment, and picturesque features, and attracting over 18 million visitors a year–on par with the holy grail of Los Angeles attractions, Disneyland. Yet, despite its prominence in Los Angeles urban leisure, little research has been devoted to this space. The Grove presents such an intriguing place as it does much more to immerse its visitors than the average mall; for one, it claims and boasts historical roots in its design and presentation–the […]

The years 31 BC AD 14 saw the Western world undergo a great revolution in culture, politics, state, and society as the regime of Caesar Augustus dismantled and replaced the centuries-old republican system of government at Rome with an imperial autocracy. In the provinces of the Roman empire, the very fabric of the city provided a key platform for the promotion of the Augustan program. However, recent reassessments of the period have begun to suggest that many of the changes in urban form during this era may instead have been […]

This year, the Church of Jesus Christ of Latter-Day Saints, commonly known as the Mormon Church, announced a worldwide membership of more than 16 million followers and growing. Their proselytizing efforts can be seen by the thousands of young men and women between the ages of 18 and 25 that devote 1.5 to 2 years of missionary service all over the world. These missionary efforts provoke a change in belief in many people which leads them to renounce old religious or secular beliefs, along with some personal freedoms in exchange […]

The human brain is characterized by ridges, or gyri, and indentations, or sulci. Individual differences in sulci have been shown to be related to aspects of cognition, which is important for our everyday functioning. Despite these findings that a) sulci develop and b) individual differences in sulci are linked to cognition in adults, no study has yet examined the relationship between the development of sulci and the development of an essential cognitive ability known as working memory. Working memory is the ability to maintain and manipulate information. It develops over […]
