For such effects \u201cbelow the detection limit\u201d, where data can only infer upper bounds, Bayesian and frequentist methods can give important complimentary information. I will begin with an overview of the frequentist profile-likelihood method, its advantages and limitations. Using a frequentist and Bayesian toolbox, I will discuss neutrino mass constraints from Planck and DESI data. In particular, I will focus on the impact of different assumptions about the neutrino mass hierarchy on the inferred mass bounds. Further, I will compare Bayesian and frequentist constraints on evolving dark energy from recent cosmological data.", "occurrence_notes":null, "guid":"145458-21897372@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145458", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Science"], "website":"", "sponsors":[ { "group_name":"HEP - Astro Seminars", "group_id":"3799", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21897372 } , "145036-21896571": { "datetime_modified":"20260204T094256", "datetime_start":"20260309T150000", "datetime_end":"20260309T160000", "has_end_time":1, "date_start":"2026-03-09", "date_end":"2026-03-09", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Intersections of AI, Photonics, and Scientific Discovery", "occurrence_title":"", "combined_title":"Intersections of AI, Photonics, and Scientific Discovery: Marin Solja\u010di\u0107, Cecil and Ida Green Professor of Physics, Masachusetts Institute of Technology", "event_subtitle":"Marin Solja\u010di\u0107, Cecil and Ida Green Professor of Physics, Masachusetts Institute of Technology", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Abstract: Artificial intelligence is beginning to transform the way we do science and engineering\u2014not only by analyzing data, but increasingly by generating hypotheses, designing experiments, and even running them. Photonics plays a dual role in this story: it provides some of the most promising physical platforms for AI hardware, while also serving as a rich testbed for applying AI itself. I will discuss how conventional \u201cblack box\u201d AI and more interpretable approaches can both uncover structure in complex systems, and how large language models point toward a future where significant parts of scientific discovery may be automated. I will also highlight how robotics, combined with AI, is moving us closer to self-driving laboratories. While my examples will often come from photonics, the broader message is that these developments foreshadow a profound shift in how science is practiced across disciplines.\n\nBio: Marin Solja\u010di\u0107 is a Professor of Physics at MIT. He is a founder of a few companies, including WiTricity Corporation (2007), Lightelligence (2017) and Axiomatic (2024). His main research interests are in artificial intelligence as well as electromagnetic phenomena, focusing on nanophotonics, non-linear optics, and wireless power transfer. He is a co-author of more than 300 scientific articles, more than 100 issued US patents, and he has been invited to give more than 100 invited talks at conferences and universities around the world. He is a recipient of the Adolph Lomb medal from the Optical Society of America (2005), and the TR35 award of the Technology Review magazine (2006). In 2008, he was awarded a MacArthur fellowship \u201cgenius\u201d grant. He is an international member of the Croatian Academy of Engineering since 2009.
