Oziel Valdez Sanchez, MC

My name is Oziel Valdez-Sanchez. I am the eldest son in my family, and I have one brother and one sister. I was born in 1990 in Monterrey, Mexico, where I graduated from ‘Universidad Autonoma de Nuevo Leon’ School of Medicine, which is the biggest university in the northeast of Mexico. I consider that I have an inquisitive mind, am someone who likes to understand the “whys” and the “hows” of the disease process, and other topics beyond medicine, and I think that pathology is the medical specialty that best matches those interests. Outside of medicine, I like to do simple things such as having a conversation on any topic with a good friend, taking a walk, contemplating the scenery and practicing meditation.

After moving to the U.S., I worked at MD Anderson Cancer Center for prostate cancer research before I was matched into the pathology residency program at Case Western Reserve University/University Hospitals. I found pathology a very promising specialty for me to pursue postgraduate medical training, since it really allows us to dig inside the pathogenesis of different diseases, and thus help us to make accurate and personalized diagnosis as well as to innovate novel therapeutics for patients. In my spare time, I enjoy swimming, cooking, watching movies and traveling, etc.


Alwalid Ammoun, MD

Hi, this Alwalid and you can call me by Waleed, as most people around me do. I was born in Syria and I grew up in different places in the Middle East. I received my medical degree from Damascus University and I moved to the United States right after graduation. I was involved in research projects at NYU, focusing on the enhanced clearance of pathological conformations of both Amyloid beta and tau proteins in Alzheimer’s disease, using both active and passive immunization approaches.

When it comes to spare time, I’m very adventurous, I like soccer and biking and I work out regularly. I enjoy reading, music, traveling and learning about different cultures and that would always include trying new recipes. Also, I’m always down for a good concert or show.

My future career goals are still open and depend on my experience during residency, and among many reasons that made me choose Case Western Reserve University/University Hospitals is the strength of both AP and CP, so I’m quite sure that will help me find my niche.

I’m very excited and proud to be part of this team, and I look forward to working with all of you.

I look forward to spending many more wonderful years here in Cleveland


Achal Acharya, MBBS

I received my medical education in Kathmandu, Nepal at KIST Medical College. After graduating from medical school I worked as a medical officer in a hospital in Nepal and was also a lab assistant at Kathmandu Path Lab prior to starting at UH. Some of the main draws of University Hospitals at CWRU for me are the strength of the Clinical Pathology division and matching strength of the Anatomic Pathology division. I look forward to engaging in research with the UH faculty on topics like the identification of molecular markers and pathways for development of novel therapeutics. Another major draw of UH for me was that it is also headquarters for the National Center for Regenerative Medicine. This is an area that I see myself working in even as a pathologist. My fellowship interests include molecular and genetic pathology. I am specifically interested in the molecular aberrations of a variety of solid tumors. My out of work interests include mystery and detective novels and film, and adventure sports. I am also an amateur sitar player.'
