Muzharul Islam is a 20th Century Bangladeshi architect.  I never heard of him until I saw that Bangladesh had added a number of his buildings to the TWHS list.  
Three of these buildings are on the campus of Dhaka University.  Dhaka University was an enjoyable place to visit.  It is quite spread out and is a mixture of buildings from the British era built in the 1920's and more modern buildings built in the 1960's when Bangladesh was East Pakistan. The three buildings by Islam were built in the 1950's and 1960's.  It is hard for me to make an informed judgement of these buildings as I tend to find modern 20th century architecture not that exciting and my least favorite WHS tend to be these modern 20th century architectural sites. From my perspective I didn't think Islam's buildings stood out from all the other modern buildings on campus, and I found the original 1920 British buildings to be the most attractive.  Though I didn't see anything special in Islam's buildings, I did really enjoy walking around campus, looking at the students, and enjoying the walk around Bangladesh's biggest University.
