My research interests include infections in the immunocompromised host, recurrent C. difficile infection and fecal transplants in cancer patients, and the effect of pneumonia vaccination on the epidemiology of Streptococcus pneumoniae infections at Memorial Sloan Kettering.
I am also actively involved in administration and the medical education of students, interns, and infectious disease fellows at MSK and Weill Cornell Medical College.

Dr. Kaltsas explained things to me very thoroughly. I find her very easy to talk to. She's very knowledgeable and I would highly recommend her to anybody who's dealing with the situation that I'm dealing with and she's very thorough.
There was a bit of a delay because, I think, of confusion that I prefer blood to be drawn from my port. Otherwise, my care was of stellar quality as usual!
Anna is such a good doctor! She is very experienced and communicates extremely well. I feel much relieved after listening to her explaining why my current doctors chose their approach and feel more empowered to deal with my situation, physically and mentally. Thank you, Anna!
Dr. Kaltsas made me feel at ease immediately. She took her time and listened to my concerns. She explained her plan to help me and explained everything clearly.
Dr was knowledgeable and informative.
