Physics Professor Steve Garoff is an award-winning advisor and teacher. But recently he\u2019s been learning a thing or two from his twin grandsons.<\/p>\n
During the height of the COVID-19 pandemic, Garoff began weekly Zoom meetings with the now-13-year-olds to discuss what\u2019s exciting about science. They talk about physics or discuss the Physiology Nobel Prize or look at images from the James Webb telescope.<\/p>\n
\u201cI\u2019m so impressed \u2014 and often stumped \u2014 by the questions these young men ask,\u201d Garoff said. \u201cThey\u2019ve renewed my enthusiasm for science. It\u2019s the best new thing I do.\u201d<\/p>\n
Garoff retired in January 2021, giving him more time to spend with his grandsons, daughter, son-in-law and wife of 47 years. He hasn\u2019t slowed down much, though. He\u2019s advising five graduate students, teaching undergraduates, serving as vice chair of the University Research Council and conducting research, including an experiment with the European Space Agency.<\/p>\n
Garoff joined the Carnegie Mellon faculty in 1988 after a career in industry. His research, which examines the physical properties of the interfacial regions between liquids and other liquids or solids, has broad impacts on a number of fields including health care and materials science. As a soft condensed matter physicist, he conducts research at the border of applied physics and engineering, leading to extensive collaborations with faculty \u2014 and to advising many students \u2014 in Carnegie Mellon\u2019s Department of Chemical Engineering, where he holds a courtesy appointment.<\/p>\n
\u201cThe focus of my research makes collaboration natural, but Carnegie Mellon made it more than possible. It made it easy,\u201d Garoff said.<\/p>\n
For Garoff, some of his fondest memories come from teaching and interacting with students.<\/p>\n
\u201cThe very best days in my entire career are graduation days and thesis defense days,\u201d he said. \u201cI feel such a sense of pride. It\u2019s just amazing.\u201d<\/p>\n
He has mentored nearly 50 Ph.D. students, master\u2019s students and postdocs and supervised more than 100 undergraduate research projects. For 26 straight years he taught Modern Physics Laboratory, the junior-level physics course. Garoff has been heavily involved in many aspects of undergraduate education in the Department of Physics from the very beginning, including during his tenure as associate department head and department head.<\/p>\n
\u201cI was very lucky. I really got to know almost all physics majors pretty darn well,\u201d said Garoff, whose dedication to undergraduate education was recognized with the university\u2019s Academic Advising Award and MCS\u2019s Richard Moore Award.<\/p>\n
Garoff credits his Ph.D. thesis advisor\u2019s thesis advisor, David Turnbull, for inspiring him to become a teacher.<\/p>\n
\u201cHe taught me that the real payoff is not so much in the science that you do but in the young people you help to become future scientists and citizens,\u201d he said.
As he looks back on his career, Garoff knows that Turnbull was right. When he bumps into an alumnus on campus or sits down to dinner with alumni at an event, he finds so much joy in catching up and reminiscing.<\/p>\n
\u201cI\u2019m so lucky to know these incredible people who span my career,\u201d Garoff said. \u201cI can\u2019t imagine anyone on this earth having a better job than I\u2019ve had here.\u201d<\/p>\n

In fairness, the calorimeter was built in pieces on Carnegie Mellon\u2019s campus, but impressive nonetheless.<\/p>\n Quinn, like most particle physicists, uses huge pieces of equipment to study the tiniest of subatomic particles. The calorimeter, for example, was built for the GMn experiment at the Thomas Jefferson National Accelerator Facility (JLab), designed to measure the magnetic form-factor of the neutron. Quinn proposed the idea for the experiment in 2010 and finally saw it come to fruition in early 2022, just as he was set to retire.<\/p>\n \u201cFor the experiment we had to build a new spectrometer \u2014 the Super-Bigbyte Spectrometer \u2014 and the new hadron calorimeter, and we repurposed a giant magnet from Brookhaven,\u201d said Quinn, emeritus professor of physics. \u201cIt was kind of cool to see it all come together.\u201d<\/p>\n Quinn, who joined the medium-energy physics group at Carnegie Mellon in 1984, has been a part of several big experiments during his career. At Brookhaven National Lab he conducted hyper-nuclear decay experiments and experiments searching for the H-particle (6-quark di-baryon). At the Low Energy Antiproton Ring at CERN, he worked on antiproton annihilation experiments, on what Quinn calls a little tabletop experiment.<\/p>\n \u201cI thought it was a very cute experiment,\u201d Quinn said. \u201cIt was one that could literally be mounted on a table \u2014 well, a big table. One grad student could roll the whole experiment around.\u201d<\/p>\n Most of Quinn\u2019s work since then has been at JLab, primarily on experiments focused on parity violation. He measured the weak interaction between the electron and proton or neutron, an interaction that violates parity. He participated in the G0 and HAPPEX-3 experiments and in the PREX experiment, which uses the weak force to probe the distribution of \u201cinvisible\u201d neutrons in 208Pb, in effect measuring the thickness of the neutron-skin outside the proton-distribution in lead.<\/p>\n \u201cParity violating experiments are very fiddly experiments in terms of the quality of the data and the quality of the systematic control,\u201d Quinn said. \u201cThey\u2019re hard, and they\u2019re cutting edge, and I\u2019m very proud of our work on these experiments.\u201d<\/p>\n Another of Quinn\u2019s greatest points of pride is his graduate students. He mentored six Ph.D. students, who have gone on to very successful careers of their own including head of the Physics Division at Los Alamos National Laboratory and professors at the University of Virginia and the High Energy Accelerator Research Organization in Japan. He also taught a wide variety of courses, including Physics 3, in which he introduced students to special relativity, general relativity and quantum mechanics.<\/p>\n \u201cMy favorite memory of those courses was being able to blow young minds by showing them how physics could be so counter-intuitive, but still be perfectly consistent,\u201d he said.<\/p>\n Quinn is keeping tabs on ongoing particle physics experiments but is happy not to be manning them himself. In retirement, instead of putting in round-the-clock shifts at JLab, he hopes to travel the world with his wife, Sandy. They have plans to snorkel and ski, with Quinn doing a little SCUBA diving when he gets the chance.<\/p>\n \u25a0 Amy Pavlak Laird [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.19.4″ background_color=”#f2f2f2″ background_image=”https:\/\/magazine.mcs.cmu.edu\/physics\/wp-content\/uploads\/sites\/4\/2019\/11\/bg_phys.png” custom_padding=”30px|0px|30px|0px|false|false” box_shadow_style=”preset6″ global_colors_info=”{}”][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.16″ custom_padding=”0|0px|0|0px|false|false” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjIzOTIifX0=@” button_text=”Faculty Notes” _builder_version=”4.19.4″ _dynamic_attributes=”button_url” custom_button=”on” button_text_color=”#FFFFFF” button_bg_color=”#EBAB21″ button_border_color=”rgba(0,0,0,0)” button_font=”|||on|||||” button_icon=”||divi||400″ button_icon_color=”#FFFFFF” button_icon_placement=”left” button_on_hover=”off” custom_css_main_element=”width:100%;” button_border_color_hover=”#e09900″ global_colors_info=”{}” button_text_size__hover_enabled=”off” button_one_text_size__hover_enabled=”off” button_two_text_size__hover_enabled=”off” button_text_color__hover_enabled=”off” button_one_text_color__hover_enabled=”off” button_two_text_color__hover_enabled=”off” button_border_width__hover_enabled=”off” button_one_border_width__hover_enabled=”off” button_two_border_width__hover_enabled=”off” button_border_color__hover_enabled=”on|hover” button_border_color__hover=”#c64800″ button_one_border_color__hover_enabled=”off” button_two_border_color__hover_enabled=”off” button_border_radius__hover_enabled=”off” button_one_border_radius__hover_enabled=”off” button_two_border_radius__hover_enabled=”off” button_letter_spacing__hover_enabled=”off” button_one_letter_spacing__hover_enabled=”off” button_two_letter_spacing__hover_enabled=”off” button_bg_color__hover_enabled=”off” button_one_bg_color__hover_enabled=”off” button_two_bg_color__hover_enabled=”off”][\/et_pb_button][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjI0MDQifX0=@” button_text=”Research Roundup” button_alignment=”right” _builder_version=”4.19.4″ _dynamic_attributes=”button_url” custom_button=”on” button_text_color=”#FFFFFF” button_bg_color=”#ebab21″ button_border_color=”rgba(0,0,0,0)” button_font=”|||on|||||” button_icon=”||divi||400″ button_icon_color=”#FFFFFF” button_on_hover=”off” custom_css_main_element=”width:100%;” button_border_color_hover=”#e09900″ global_colors_info=”{}” button_text_size__hover_enabled=”off” button_one_text_size__hover_enabled=”off” button_two_text_size__hover_enabled=”off” button_text_color__hover_enabled=”off” button_one_text_color__hover_enabled=”off” button_two_text_color__hover_enabled=”off” button_border_width__hover_enabled=”off” button_one_border_width__hover_enabled=”off” button_two_border_width__hover_enabled=”off” button_border_color__hover_enabled=”on|hover” button_border_color__hover=”#c64800″ button_one_border_color__hover_enabled=”off” button_two_border_color__hover_enabled=”off” button_border_radius__hover_enabled=”off” button_one_border_radius__hover_enabled=”off” button_two_border_radius__hover_enabled=”off” button_letter_spacing__hover_enabled=”off” button_one_letter_spacing__hover_enabled=”off” button_two_letter_spacing__hover_enabled=”off” button_bg_color__hover_enabled=”off” button_one_bg_color__hover_enabled=”off” button_two_bg_color__hover_enabled=”off”][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" New FacultyValentina Dutta Valentina Dutta joined the Department of Physics as an assistant professor in 2022.
