Season 2 features physicists who play key roles in Snowmass, the US particle physics planning community. 

Episode 1 (flyer) (transcript)
Prof. Gordon Watts (he/him) 
University of Washington

I am an experimental particle physicist, and when I'm not doing that I'm trying to teach myself to take pictures and cook. My research is focused on searching for Hidden Sector extensions to the Standard Model, mostly by looking for evidence of long-lived massive particles. I love the opportunity that physics gives me to explore the internal  workings of the world around me. I also have really enjoyed working on  the computing aspects of the field - bringing more modern tools into our searches for new physics.

Prof. Alexy A. Petrov (he/him)
Wayne State University

I am a particle physicist at Wayne State University. I also like art. My research is on application of effective field theories to particle physics phenomenology. I love my research because I get to understand why the Universe is the way it is. 

Episode 3 (flyer) (transcript)
Dr. Petra Merkel (she/her)
FermiLab

I am an experimental collider physicist, who specializes on detector instrumentation, and I also love traveling, reading, movies, jigsaw puzzles, listening to live music and learning to play the piano. In the past I have been involved in the Higgs boson discovery, but now I specialize on designing and building silicon trackers and on  coordinating generic detector R&D for the High Energy Physics community. I love my research, because it requires a lot of creativity, allows me  to learn something new every day, and leads me to work with a very diverse group of people, who are all extremely good at what they are doing. Snowmass turned out to be a lot of work at a very challenging time during the pandemic, but I feel it is important to help define and shape  the future of our field using my expertise in detector instrumentation. 

Episode 4 (flyer) (transcript)
Dr. Kate Scholberg (she/her) 
Duke University

I'm particle physicist who was born in the UK, grew up in Canada and now lives in Durham, North Carolina; I also enjoy fossils, hiking, and sitting on my porch. I study neutrinos, and work on several  experiments--- COHERENT at the Spallation Neutron Source, the Deep Underground Neutrino Experiment and Super-Kamiokande-- to look for physics beyond the standard model and to understand astrophysical  objects.  I love how neutrinos connect broadly to different areas—particle physics, astrophysics and nuclear physics -- and how they  have brought surprising insights over the decades. I'm excited to be a co-convener of the Snowmass Neutrino Frontier, to explore the many future opportunities for fundamental physics with neutrino experiments..

Episode 5 (flyer) (transcript)
Dr. Benjamin Nachman (he/him)
Lawrence Berkeley National Lab

I am a Lawrence Berkeley National Laboratory physicist, and I also enjoy running and squirrel watching. I develop and deploy computational techniques to explore the fundamental and emergent properties of the strong force. Machine learning and other computational techniques build bridges between areas of physics and beyond. As a co-convener for the Computational Frontier at Snowmass, I'm excited  to see Machine Learning and Quantum Computing emerge as themes in this year's Snowmass! 

Episode 6 (flyer) (transcript)
Prof. Laura Baudis (she/her)
University of Zurich, Switzerland

I am a Romanian-born German-Swiss astroparticle physicist and I also enjoy reading poetry, hiking and kayaking on Swiss lakes. My research is focused on the direct detection of particle dark matter with xenon time projection chambers and on the search for neutrinoless double beta decay with enriched germanium crystals operated in liquid argon. I love the fact that these rare-event searches pose formidable challenges to our detector technologies, requiring new detector prototypes that we must develop and test in the lab. I also enjoy working with many enthusiastic researches in our international  experimental collaborations. To me Snowmass is a very important grass-roots process in particle and  astroparticle physics, not only relevant for USA, but with international relevance and implications. I am also excited to be one of the  conveners for the Underground Facilities Frontier. 

Episode 7 (flyer) (transcript)
Prof. Meenakshi Narain (she/her)
Brown University

I am an Asian-Indian American Physicist, who traveled from Gorakhpur, UP, India and finally settled in Providence, RI USA, with my German husband and two sons. I am passionate about cooking and organizing events which meld scientific concepts with arts and music. My research focuses on investigating the early universe moments after the Big Bang created in small and large particle colliders, by building  innovative scientific instruments (detectors) to explore and find  fundamental particles and their interactions, and through these experiments unravel mysteries such as the origin of matter, the types of matter in the universe and many more. I love my research, as it gives me a purpose, and gives me an  opportunity to forge an inclusive partnership with a diverse set of  researchers who help me connect with the  age-old quest of humankind to  understand where we come from, why we are here, and eventually visualize  the building blocks of our home, the universe! I am humbled to have been chosen as one of the leaders of the Energy  Frontier group of the broader Snowmass study to help formulate a  community wide vision to explore the TeV energy scale and beyond with  future collider options, which will define the landscape of experimental  opportunities over multiple decades [and late into this century]. 

Episode 8 (flyer) (transcript)
Dr. Kétévi Adiklè Assamagan (he/him)
Brookhaven National Laboratory

I am a Black physicist, originally from Togo. I enjoy playing Djembe and swimming. I do research on the ATLAS experiment searching for dark sector states beyond the standard model of particle physics. Working with people, learning from them and getting my ideas challenged. Through Snowmass, I've met and worked with many new people; that won't have been possible otherwise. 

Episode 9 (flyer) (transcript)
Prof. Tao Han (he/him/his)
University of Pittsburgh 

I am a theoretical particle physicist, specializing in collider phenomenology, a theoretical branch that builds the bridge between theory and experimental observations. To explore new physics beyond the Standard Model, I formulate theoretical models and predict observables at colliders as well as at low energy experiments. The topics I have been interested in include Higgs boson physics, searching for dark matter, examining neutrino mass generation models. I closely collaborate with my colleagues in theory and experiments. Since 2019, I have been involved in organizing the community planning exercise, a.k.a. "Snowmass 2021", led by APS DPF. The particle physics community comes together to identify fundamental questions in the field and the opportunities to address.  The Snowmass exercise is very important for our field in the next decay and beyond. The final community meeting will take place in July 17-26, 2022, at the University of Washington-Seattle. 

Episode 10 (flyer) (transcript)
Prof. Marcelle Soares-Santos (she/her)
University of Michigan

Professor Soares-Santos’ research aims to uncover the nature of the accelerated expansion of the cosmos. Her team detected the first neutron star collision ever observed, a discovery heralded as the Science breakthrough of the year 2017. She was awarded the prestigious Sloan Research Fellowship in 2019 and the Cottrell Scholar Award in 2021. Her research has been featured in major media outlets worldwide including the PBS TV series Nova Wonders. Previously, Professor Soares-Santos was the Landsman Career Development Chair & Assistant Professor of Physics at Brandeis University. She was also an Associate Scientist at the Fermi National Accelerator Laboratory. 

Episode 11 (flyer) (transcript)
Dr. Julia Gonski (she/her)
CERN, Switzerland

I am a high energy experimental physicist, searching for new fundamental particles using the Large Hadron Collider at CERN in Geneva, Switzerland. My work is split between data analysis, where I focus on the application of novel machine learning methods such as anomaly detection to enhance our discovery potential, and detector development, namely upgrading the readout electronics for the liquid argon calorimeter of the ATLAS experiment. This variety means that in a single work day I can go from working hands-on with engineers on a printed circuit board setup, to testing training algorithm configurations, and end with a hundred-person meeting, and I am always energized by the fast pace gear shifts! This Snowmass process will bring together experts across these disparate activities and prepare recommendations on the future course of the field, and my role is to facilitate the participation of early career physicists in the conversation. Outside of physics, I enjoy mixed martial arts, skiing, and struggling to learn French. 

Episode 12 (flyer) (transcript)
Prof. R. Sekar Chivukula (he/him)
University of California, San Diego

I am an American theoretical particle physicist of Indian origin, and I also enjoy hiking, travel, and meditation. I study theories of the origin of electroweak symmetry breaking and flavor physics, and their possible signatures at high-energy colliders. I love using mathematical tools and models to understand and make predictions about the physical world around us. I serve as DPF Chair Elect and on the Snowmass Steering Committee.
