    Scholarship & Awards: Dr. Kitavi was awarded Hong Kong PhD Fellowship by the Hong Kong Research Grants Council to pursue a Doctor of Philosophy Program at the Hong Kong Polytechnic University, 2014 – 2017. The 3-year Fellowship provided a monthly stipend of 20,000 Hong Kong Dollars and a conference and research related travel allowances of 10,000 Hong Kong Dollars per year. In addition, The Hong Kong Polytechnic University supplemented the award by offering a 3-year tuition scholarship. The Hong Kong PhD Fellowship Scheme (HKPFS) was established by the Hong Kong Research Grants Council in 2009 to attract the best and brightest students in the world to pursue their PhD programmes in Hong Kong universities.Dr. Kitavi also received Master of Science degree scholarship by the African Institute for Mathematical Sciences (AIMS), South Africa, 2012 – 2013. The scholarship covered all expenses (travel, tuition, research, boarding, medical insurance, and a monthly stipend) during the entire period of study. AIMS is an academic network whose goals are to promote mathematics and science in Africa and to build capacity for African initiatives in education, research, and technology. Dominic also received an ABSA Bursary Award of 26,500 South African Rand in 2013 to support his Master Degree study.
