He was named medical director of Clinical Research at College of Health Solutions and is one of the founders of the Translational Research Center at Arizona State University.
 LoVecchio's research mainly focuses on ketone levels in the lungs and blood, and pesticide exposures and scorpion stings in young children. He has advocated in the legal arena regarding medical toxicology, emergency medicine, addiction, product safety and public health issues, and has also worked as an on-air expert on topics including, public health, opioid crisis, and COVID-19. He was featured in National Geographic’ Drugs, Inc. Flesh-Eating Krokodil episode.
 He has received funding to study suicide prevention, respiratory diseases, CPR, sepsis, and MRSA infections.
 In a February 2021 New York Times documentary following Valleywise healthcare workers, LoVecchio gave positive remarks on the expected future COVID-19 situation in Arizona. In September of that year, he was part of a study that conducted a test-negative case-control investigation regarding the effectiveness of Moderna COVID-19 vaccine among U.S. health care personnel.
 In 2014, LoVecchio conducted a multicenter trial in the tertiary care setting, and found out that protocol-based resuscitation of patients in whom septic shock was diagnosed in the emergency department did not improve outcomes. In his paper published in 2010, he investigated the survival rate of patients with out-of-hospital cardiac arrest using compression-only CPR (COCPR) compared with conventional CPR. Results of his study showed that layperson compression-only CPR was associated with increased survival in comparison to conventional CPR and no bystander CPR in this setting with public endorsement of chest compression–only CPR.
 LoVecchio also investigated the influence of the infecting pathogen on the hospital length of stay (LOS) for acute bronchiolitis. He determined that RSV was more frequently detected virus in children hospitalized with bronchiolitis, as compared to HRV; which was detected in one-quarter of the children. Furthermore, he studied procalcitonin-guided use of antibiotics in context of lower respiratory tract infection.
 In 1997, The dogma of avoiding analgesics in patients with acute abdominal pain  was challenged, and in one of the first studies addressing this issue, LoVecchio and his colleagues, concluded that physical examination does change after the administration of analgesics in patients with acute abdominal pain. He also conducted a study to determine the impact of ED-initiated intervention in terms of subsequent suicidal behavior.
 LoVecchio published a paper in 2008 focused on how poison control centers decrease emergency healthcare utilization costs, and determined that the home management by Banner Poison Control Center provided large monetary savings to residents in comparison to dollars received in state support. He also focused his study on the centruroides sculpturatus and regarded it as the only scorpion native to the United States whose venom produces life‐threatening illness. He studied the distribution of the severity grades following scorpion envenomations, the time to deterioration, the onset of clinical signs and symptoms, and side effects regarding the antivenom treatment in children of particular age.
 LoVecchio reviewed poison center data charts from January 2007 through December 2009, and discussed the outcomes of unintentional beta-blocker or calcium channel blocker overdoses among patients. Furthermore, he conducted a 5-year retrospective poison control center review and explored the outcomes regarding chlorine exposure in 598 patients.
