Social and Personality Psychology
Lucylle (Lucy) Armentano is a fifth-year PhD candidate in Social and Personality Psychology at Yale. Her dissertation examines the potentially differential functions of verbal and nonverbal emotional expressions for building close relationships. Lucy’s research illustrates that verbal emotional expressions are linked to greater commitment in the relationship whereas both verbal and nonverbal expressions are linked to greater responsiveness and trust in one’s partner. Lucy was privileged to mentor almost 30 undergraduate research assistants during her graduate studies, many from traditionally underrepresented backgrounds. This included designing a novel seminar course focused on research skills and professional development and mentoring students through the process of applying to graduate programs. Lucy developed a passion for advocating for graduate students through her service activities. As Chair of the Graduate Student Assembly, she had the opportunity to advocate for the needs of graduate students within the highest levels of the university administration. Central to her platform as Chair was a diversity initiative, in partnership with the Office for Graduate Student Diversity and Development, to understand how graduate students conceptualize diversity and its importance within graduate studies. In addition, Lucy has also served on numerous university-wide and departmental committees, including the IRB’s Human Subjects Committee to review and approve human subjects research and the Psychology Department’s Space Steering Committee to represent students in the design of a new departmental space, among others. In recognition of years of service to graduate students, Lucy was awarded the Department of Psychology’s Jane Olejarczyk service award in 2020.
Sociology and African American Studies
As a doctoral candidate in Sociology and African American Studies at Yale University, Demar Lewis’s research leverages multiple methods to broadly examine health consequences of lynching, policing, and social inequities in the United States. Since Spring 2018, Demar has served as the academic collaborator to the Monroe and Florence Work Today Project, which represents the largest, nationally-encompassing inventory of U.S. lynchings spanning 46 states. In another project, he is working with scholars at Harvard University and Columbia Law School to produce an original, publicly-available dataset of media-tracked police killings between 2004-2017 to strengthen future empirical analyses of fatal police violence. From 2017-2019, Demar served as a research assistant for the Portals Policing Project championed by faculty at Yale Law School’s Justice Collaboratory, where he held significant data management and thematic interview coding responsibilities. Demar has cultivated an exciting dissertation project that is certain to make strong contributions to academic and policymaking circles. His dissertation, Black Ideologies of Community Safety in the 21st Century, examines how Black people’s lived experiences shape their perceptions of the institution of U.S. policing and community safety priorities, attentive to how these perceptions and priorities vary by socioeconomic status and neighborhood of residence. Topically, Demar’s dissertation contributes to interdisciplinary debates in Sociology, Criminology, Political Science, and Black Studies while advancing knowledge in the substantive areas of policing, inequality, and racial discrimination. As 21st Century calls to “defund the police” proliferate, Demar’s dissertation reveals how addressing the perennial health needs and safety concerns of Black residents across class strata are inextricably linked.
Shanelle Shillingford is an immigrant from the Commonwealth of Dominica, and currently a fifth-year PhD candidate in the Chemistry Department at Yale. Her research interest focuses on a protein phosphatase, known as MKP5. Mitogen-activated protein kinase (MAPK) phosphatase 5 (MKP5) is a dual-specificity phosphatase (DUSP) whose aberrant function has been linked to several diseases involving inflammation and fibrosis, including muscular dystrophy. MKP5 belongs to a subgroup of DUSPs called MKPs, that dephosphorylates the MAPKs; serine/threonine kinases that play important roles in cell proliferation, death, and migration. These MAPKs have also been linked to many diseases, and as such, are actively studied as therapeutic targets, with several small molecule drugs already successfully developed. However, development of their regulatory MKPs as potential therapeutic targets, has proven difficult. High sequence similarity within the catalytic domain and a negatively-charged active site has largely designated the MKPs as “undruggable” and has limited insight into their mechanisms of action. Progress has been made on this front, with the discovery of a low potency, allosteric inhibitor of MKP5. This small molecule required further development for improved potency but served as an excellent explorational tool into MKP5’s mechanism of action that led to the discovery of a novel allosteric site. Interestingly, while this allosteric site shares sequence similarity across MKPs, this small molecule had high specificity for MKP5. To this end, further exploration of this site in MKP5 and other MKPs using mutagenesis, cell-based activity assays and other biochemical assays have revealed that this site modulates activity and signaling differently amongst the MKPs. This discovery holds the potential for greater knowledge into MKP functionality and a new approach for the development of MKP inhibitors for the treatment of certain human diseases.
African American Studies and English
Cera Smith (they/she) is a fifth-year PhD candidate in African American Studies and English at Yale. Their dissertation research analyzes representations of the Black internal body in 20th- and 21st-century U.S. Black literature and visual art. Cera does so by putting literary studies, Black Studies, the study of visual art, and the medical and health humanities into conversation. Dominant American literary criticism treats “interiority” as synonymous with psychology, emotions, and consciousness. While these themes remain relevant, Cera’s research approaches the topic of interiority from the angle of the biological. Cera investigates how and why depictions of internal bodily processes and somatic experience show up in U.S. Black writing. Besides research, Cera spends their time teaching classes on U.S. Afro-Latinx literatures and African Americanness, where students explore the complex relationships between race, ethnicity, and nationality. Cera works as a Fellow for Yale’s Office for Graduate Student Development and Diversity, specializing in recruitment and retention of underrepresented graduate students through the Transitions Program. They also work as a Degree Coordinator Fellow for the Yale Prison Education Initiative, where they are building out an associate degree program for incarcerated students in partnership with the University of New Haven. Outside of school, Cera supports local community organizations working towards racial justice, such as CT Community Organizing for Racial Equity (CTCORE)—Organize Now!.
History and African American Studies
Brandi Waters is a Ph.D. candidate in the departments of History and African American Studies. Her dissertation, “Debating ‘defects’: Slavery, Disability, and Legal Medicine in Late Colonial Colombia” examines how ideas about health and the body impacted the implementation of slavery laws and the practice of legal medicine in the last half-century of Spanish colonial rule in Colombia, then known as New Granada (approximately 1760-1810). This research employs archival methods and analyzes various sources, such as contract disputes, medical treatises and evaluations, and trial records from archives in Colombia, Spain, and the United States. It uncovers how enslaved people with health “defects” (chronic illnesses and disabilities) endeavored to use the law strategically to gain access to healthcare and to avoid health threats. Through close analysis of four legal mechanisms, this research illustrates how medical and legal authority combined to create the stakes of becoming chronically ill or disabled while enslaved. Enslaved people, in turn, responded by leveraging medico-scientific ideas and relying on medical evaluators in their legal petitions. Ultimately, this dissertation illustrates slavery’s connections to debates about medical ethics and the early practice of legal medicine in Latin America. It also contextualizes the long history of Afro-Colombians’ ongoing struggles against medical disparities and juridical inequities.
