What are your favorite things about the fellowship?
The experience in the MICU! We are treated as peers by the attendings as we take care of the sickest patients in the hospital. The MICU is a special place where there is an engrained culture of respect and collaboration between the doctors, nurses, RTs and administration that doesn't exist anywhere else in the hospital.  It's truly a joy to come to work every day! 
What do you love about New York City? 
There is never a moment of boredom in NYC.
What do you like to do outside of work?
Spending time with friends and family, relaxing in the park and visiting the Met.

What are your favorite things about the fellowship?
Our fellowship has superb procedural and airway training, approachable faculty, and a great learning environment.
What do you love about New York City? 
The restaurant scene is amazing. There’s always something interesting to do whether inside or outdoors.  
What do you like to do outside of work?
Walk my dog in Central Park, go to a new restaurant, read, and spend time with family and friends.

  • B.A.: Barnard College New York
  • D.O.: New York Institute of Technology College of Osteopathic Medicine
  • Residency: NYU Grossman School of Medicine

What are your favorite things about the fellowship?
The community at Weill Cornell within the division and fellowship. It truly feels like a family and the support is unparallel.  
What do you love about New York City? 
There is so much to explore! As someone who has always lived in NYC, I am still finding something new to see or do every weekend.  
What do you like to do outside of work?
Chasing my son around the parks of Queens or spending time with friends around downtown Brooklyn. When motivated, I try to squeeze in a spin or pilates class!   

Dr. Aaron Landau

Aaron Landau, M.D.
  • B.A.: Boston University
  • M.D.: University of Pittsburgh School of Medicine
  • Residency: NYU Grossman School of Medicine

What are your favorite things about the fellowship?
I love having the opportunity to lead rounds in the ICU. We are given a ton of autonomy from our amazing attendings to make decisions and do bedside teaching, but never without the support we need for our level of training.
What do you love about New York City? 
The food! You barely need to leave your own neighborhood to have access to all of your favorites. 
What do you like to do outside of work?
I enjoy cooking (I make a mean homemade pasta), playing music (guitar, bass, mandolin) and watching terrible reality tv with my wife.

Dr. Benedict Osorio

Benedict Osorio, Jr., M.D.
  • B.S.: Loyola University
  • M.D.: Rutgers, Robert Wood Johnson Medical School
  • Residency: Weill Cornell Medical Center/NewYork-Presbyterian

What are your favorite things about the fellowship?
Being in the ICU and our procedure suite. In the ICU, we’re able to practice the gamut of medicine, from stabilizing critically-ill patients to helping get people out of the hospital. In the bronchoscopy suite, we get to do a variety of different procedures with a ton of monitored autonomy. 
What do you love about New York City? 
Exploring all of the neighborhoods, specifically the food! There’s always something to do and there’s no where else in the world with the amount of variety when it comes to the different neighborhoods. You can travel to a whole other world after a quick subway ride. 
What do you like to do outside of work?
Mastering the New York Times games, relaxing in Central Park, and watching a ton of different movies (just missed the Tribeca film festival this year!)
