She is a fellow of the American College of Sports Medicine (ACSM), past member of the Board of Trustees of ACSM, and past president and former department chair of the Mid-Atlantic Regional Chapter of ACSM. Since 2005, she has provided [[Two-day cardiopulmonary exercise test|2-day cardiopulmonary exercise testing]] (CPET) for persons with [[ME/CFS]] for purposes of research and/or to provide an objective assessment of functional capacity and ability to perform and recover following physical work for disability reports. She studies the effects of physical activity in ME/CFS on parameters of physiological and immune function.<ref name="committeebio">{{Cite book | url =https://www.ncbi.nlm.nih.gov/books/NBK284904/ | title = Biographical Sketches of Committee Members, Consultants, and Staff | first = | last = ((Committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome))| first2 = | last2 = ((Board on the Health of Select Populations))| first3 = | last3 = ((Institute of Medicine)) | author-link3 = Institute of Medicine | date = 2015-02-10| publisher = National Academies Press|location=US|language=en}}</ref> In 2015 Keller said "Given what we have learned in the past eight years about this illness, it is intellectually embarrassing to suggest that ME is a psychological illness."<ref>{{Cite web | url = https://niceguidelines.blogspot.com/2015/01/exercise-physiologist-prof-kellerit-is.html | title = THE NICEGUIDELINES BLOG: Exercise physiologist Prof Keller: it is intellectually embarrassing to still suggest that ME is a psychological illness | last = Speedy | first = Dr | date = 2015-01-22 | website = THE NICEGUIDELINES BLOG | access-date = 2019-10-11}}</ref> In 2017, Dr. Keller became an exercise physiology researcher at the [[Center for Enervating NeuroImmune Disease]], Cornell University, New York, an ME/CFS Collaborative Research Center partially funded by the [[National Institutes of Health|NIH.]]<ref name="neurocirnell">{{Cite web | url = http://neuroimmune.cornell.edu/ | title = Cornell Center for Enervating NeuroImmune Disease | website = neuroimmune.cornell.edu|language=en-US | access-date = 2018-08-09}}</ref> == Boards and committees == ===Institute of Medicine committee=== Keller was one of the experts on the "Committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome" that was convened for the 2015 [[Institute of Medicine report]].<ref name="committeebio"/> ===ME/CFS Common Data Element (CDE) Project=== Member of the Post-Exertional Malaise Working Group and Quality of Life/Functional Status (CPET)/Activity Working Group of the Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Common Data Element (CDE) Project sponsored by the [[National Institute of Neurological Disorders and Stroke]] and the [[Centers for Disease Control and Prevention]].<ref>{{Cite web | url = https://www.commondataelements.ninds.nih.gov/Myalgic%20Encephalomyelitis/Chronic%20Fatigue%20Syndrome#pane-138 | title = Complete Myalgic Encephalomyelitis/Chronic Fatigue Syndrome CDE Roster | last = | first = | author-link = | date = | website = NIH|archive-url=|archive-date=|url-status= | access-date = 2019-10-11}}</ref> ==Notable studies== *2014, Inability of [[ME/CFS|myalgic encephalomyelitis/chronic fatigue syndrome]] patients to reproduce [[VO2 Max|VOโpeak]] indicates functional impairment<ref>{{Cite journal | last = Keller | first = Betsy A | author-link = Betsy Keller | last2 = Pryor | first2 = John | last3 = Giloteaux | first3 = Ludovic | author-link3 = Ludovic Giloteaux| date = 2014 | title = Inability of myalgic encephalomyelitis/chronic fatigue syndrome patients to reproduce VO2peak indicates functional impairment | url = http://translational-medicine.biomedcentral.com/articles/10.1186/1479-5876-12-104 | journal = Journal of Translational Medicine|language=en | volume = 12 | issue = 1 | pages = 104|doi=10.1186/1479-5876-12-104|issn=1479-5876|pmc=|pmid=24755065|via=}}</ref> [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4004422/ (Full Text)] *2016, A Pair of Identical Twins Discordant for [[ME/CFS|Myalgic Encephalomyelitis/Chronic Fatigue]] Syndrome Differ in Physiological Parameters and Gut Microbiome Composition<ref name="Giloteaux2, 2016" /> *2018, Eukaryotes in the [[Gut|gut microbiota]] in [[ME/CFS|myalgic encephalomyelitis/chronic fatigue syndrome]] [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5784577/ (Full Text)]<ref name="Mandarano, 2018" /> *2018, Cardiopulmonary Exercise Test Methodology for Assessing [[Exertion]] Intolerance in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome<ref>{{Cite journal | last = Stevens | first = Staci | author-link = Staci Stevens | last2 = Snell | first2 = Chris | author-link2 = Christopher Snell | last3 = Stevens | first3 = Jared | last4 = Keller | first4 = Betsy | author-link4 = Betsy Keller | last5 = VanNess | first5 = J.
