Dr Menberework Chanyalew, Negatue, PhD, studied biology (BSC) and Parasitology (MSC) at Addis Ababa University. She has been working as a researcher at Armauer Hansen Research Institute (AHRI), Addis Ababa, Ethiopia since 2004. She also worked as a lecturer at Dilla and Addis Ababa University, Ethiopia for more than 10 years. She conducted her doctoral project on innate immunity in cutaneous leishmaniasis in Professor Tamas Laskay group in University of Lübeck, Germany, and AHRI, Addis Ababa, Ethiopia. After completing PhD, She works as postdoctoral research fellow under the mentorship of Dr. Rawleigh Howe where she studies innate and adaptive immune response in Podoconiosis at AHRI. In addition, she also supervised postgraduate students who work on cutaneous leishmaniasis. Dr. Menberework Chanyalew is an assistant professor at the Bahir Dar University. Upon completion of her post-doctoral study, Menberework plans to pursue her career as an independent researcher in the field of immunology of cutaneous leishmaniasis and tuberculosis and contribute to the development of new vaccines and therapies.
