EXPERTISE:

• Epidemiology (including COVID-19)

• Statistics

• Research Methods

• Psychology/Mental Health

I am a full professor in the School of Social & Behavioral Sciences at Mercy University. My professional expertise encompasses epidemiology, statistics, education, research methods, and mental health, with a teaching and research emphasis on statistical literacy and evidence-based practice in the health and behavioral sciences. I also provide media commentary on infectious diseases, including COVID-19 (see selected media appearances and publications).

• "These vaccines continue to significantly reduce the risk of severe illness, hospitalization, and death -- and that's an amazing scientific feat amidst a deadly pandemic. Attention to timely and effective messaging to healthcare providers and the general public should be a top priority for the FDA. Semantics matter. " Medpage Today, January, 2022

• “As we move forward with the booster dose in certain populations, the variability in the effectiveness of the COVID-19 vaccines is sure to fuel the debate about the need for heterologous boosting, also known as mix and match.” Medpage Today, September, 2021 

• “Undoubtedly, [the vaccine mandates] are very effective tools if fully implemented and properly enforced, but that is fraught with challenges,” says Rossi Hassad, an epidemiologist at Mercy University in New York. “So, there will be many cracks in the system that unfortunately may prolong this pandemic.” National Geographic, September, 2021

• “Real-world data is messy data,” he said. “And because it’s messy, we want it, because it reflects the real context in which people live and operate.”

• “When you have data that are broad in scope, you have to approach them with a mindset of discovery,” said Hassad. “If everything is hypothetical and deductive in our reasoning”—as is the case with controlled trials—“then there is no room for creativity and discovery.” APA Monitor on Psychology, September, 2021

• “Rossi A. Hassad, an epidemiologist and statistician at Mercy University in Dobbs Ferry, N.Y., reported this month that both viruses “share key transmission characteristics.” Dr. Hassad and other experts say that what is known about the flu virus can inform our understanding of how and why Covid-19 is likely to become even more hazardous in the months ahead and that this knowledge can, in turn, reinforce the advice that everyone adopt readily available measures to thwart it.” New York Times, November, 20, 2020

• Hassad adds: “The standard set by the mRNA vaccines — in terms of speed of development and the level of efficacy and effectiveness — will quite likely raise the bar in terms of public expectations: wanting more, better, and faster when it comes to … vaccines for other diseases.” If a doctor recommends a particular vaccine, he explains, “I can hear people saying, ‘How good is that vaccine? How effective is it? Is it good for people like me? Are there any factors about my life that I need to consider?’ I think it’s just really upped the bar in terms of patient education in their personal health — which, of course, will contribute to their decision-making about health.”  National Geographic, May, 2021

• The more plausible lab-leak hypothesis, scientists say, is that the Wuhan laboratory isolated the novel coronavirus from an animal and was studying it when it accidentally escaped. “Not knowing the extent of its virulence and transmissibility, a lack of protective measures [could have] resulted in laboratory workers becoming infected,” initiating the transmission chain that ultimately resulted in the pandemic, says Rossi Hassad, an epidemiologist at Mercy University. But Hassad adds he believes that this lab-leak theory is on the “extreme low end” of possibilities, and it “will quite likely remain only theoretical following any proper scientific investigation,” he says. National Geographic, June, 2021
