Postdoctoral Scholar, Physics
Current Research and Scholarly InterestsI am interested in topics at the crossover between Particle Physics and Cosmology, focusing in particular on dark matter, gravitational waves, non-Gaussianities, Higgs metastability and early universe.
My main area of interest is Dark Matter, and I have worked on various classes of candidates, ranging from WIMPs (particles with masses and interaction strengths comparable to the Standard Model particles, who are currently the target of many experimental searches) to Primordial Black Holes (hypothetical black holes that could have formed in the early history of the Universe) and axions (particles which would also solve the strong CP problem in particle physics).
Concerning the production mechanism for Dark Matter, I have been studying gravitational production during inflation, which is a well-motivated and minimal scenario and can guide the identification of benchmarks for direct detection.
I am also very interested in stochastic backgrounds of primordial gravitational waves. Their potential discovery would disclose precious information on the cosmology of the early universe, and the particle content at high energy scales. -
Manuel Razo-Mejia
Postdoctoral Scholar, Biology
BioI was born and raised in central Mexico, in a state called Guanajuato. Although I was trained as an engineer due to social circumstances, my passion always resided in the natural world and the way to understand it that physics offered. Guided by this passion, I did my Ph.D. with Rob Phillips at Caltech, working at the interface between physics and biology. For my postdoc, I want to bring the Physical Biology mindset to the question of evolution. That is why I joined Dmitri Petrov's lab to study the evolutionary dynamics of microbial populations from a theory-experiment dialogue perspective.

Juan Felipe Riaño
Postdoctoral Scholar, Economics
BioJuan Felipe Riaño is a postdoctoral fellow at the King Center. He is an applied microeconomist with research interests spanning the fields of political economy, development economics, and economic history. His current research agenda focuses on understanding the determinants of state capacity in developing countries and the long-term impact of conflict and historical institutions on economic development. More recently, he has been interested in the organizational economics of public sector institutions and the role of cybersecurity in modern states. He received a Ph.D. in economics from the University of British Columbia in 2022 and will join the economics department at Georgetown University as an assistant professor in August 2023.

J. Luis Rodriguez
Postdoctoral Scholar, Political Science
BioI have a Ph.D. in Political Science from the Johns Hopkins University. My research centers on how developing countries build and maintain limits on the use of force in international law. I focus on the origins of the nuclear order primarily from a Latin American perspective. My work reconstructs the attempts of the Brazilian and Mexican governments to delegitimize the threat and use of nuclear force while securing access to peaceful nuclear technologies. By analyzing the Latin American participation in the crafting of nuclear weapon nonproliferation treaties, I aim to understand how developing countries react when technological advancements challenge existing limits on the use of force.
I served as a Nuclear Security Fellow with the Fundação Getulio Vargas in São Paulo, Brazil. Before joining the Ph.D. program at Hopkins, I was a junior advisor to the Mexican Vice-Minister for Latin American Affairs, working on international security cooperation in the region.
