Give a brief summary (250 words or less) of your current area of research.

I am a theoretical high energy physicist. My work is focused on extending our understanding of what is called the “Standard Model” (SM) of particle physics which describes the known matter content of the Universe and the forces that govern their interactions. In 2012 the last piece of the SM, the Higgs boson, was discovered at the Large Hadron Collider (LHC). However, we know that something not part of the SM called Dark Matter (DM) makes up the vast majority of matter in the Universe.

One astounding fact is that the vacuum is not empty, rather, the Higgs field permeates it and gives it an energy about ~250 times that of the proton mass. Fluctuations of this vacuum energy is what we perceive as the Higgs boson. Interactions of the matter fields with this background energy is what gives rise to the observed particle masses. However, we have no understanding of why the vacuum has this very specific energy. Tantalizingly, with our current understanding of the thermal evolution of the Universe, one naturally obtains the correct amount of DM in the Universe if the DM mass is about the order of magnitude of the Higgs vacuum energy and has similar interactions.

In recent years I have proposed models where multiple Higgs fields exist, but the SM sees only one particular vacuum energy configuration. Such models have included extra matter fields which may be possible DM candidates. These models generate signals that may be probed at the LHC, correlated with possible DM observations at various land and space based astrophysical experiments, in the near future.

How did you arrive at your current area of research?

I very boringly knew that I wanted to pursue a career as a physicist when I first studied it as a separate subject in middle school. As a senior in undergrad, I was firmly decided on theoretical high energy physics. Graduate school reaffirmed that decision.

What do you see as a current emerging area of research that you would like to participate in and why?
As a theoretical physicist, the problems I work on are long standing. However, there is constant dynamical evolution of our understanding driven by advances in both theoretical and experimental physics. There are currently many high energy experiments collecting data as well as astrophysical observatories, and gravitational wave experiments. Some future directions I am thinking about are investigating connections of the evolution of the Higgs vacuum energy in the early Universe with the possibility of producing detectable gravitational waves now, which may explain why something exists rather than nothing in the Universe.
Tell us your (one) favorite STEM research paper or book.   Why it is your favorite?
I highly recommend “The Disordered Cosmos” by Chanda Prescod-Weinstein.
Do you have a favorite scientist, engineer or other role model? Who is it and why?
I don’t have one favorite. Throughout my career I have been very fortunate to have several mentors who have been instrumental in shaping me as a physicist and as a person. As a graduate student, my advisor Carlos Wagner was incredibly supportive, specially about having a family. As a postdoctoral fellow both Marcela Carena and Katie Freese were inspirational role models to me, as women who are at the top echelons of our highly male dominated physics world. I am fortunate to count them all as close friends and collaborators.     
What do you do for fun outside of your role as a woman in STEM?
I love reading, mostly fiction: sci-fi and fantasy. I also enjoy painting/sketching and baking when I have the time.
