Appearance and how the Nanofilter® works:

Testimony – IMPACT; Happy healthier customer

Dr. Askwar Hilonga is featured on the Video with Bill Gates and other world renown dignitaries and got connected to His Royal Highness The Duke of York, Prince Andrew. He is the winner of 5 reputable awards, including Pitch@Palace Global, Pitch@Palace Africa, and the Africa Prize for Engineering Innovation 2015, Sponsored by the British Royal Academy of Engineering -he invented a “Low-Cost Water Filter (Nanofilter®)”. Has 1 Patent, 1 Trademark, published 43 Articles by Dec 2018, authored 2 books, and 1 Book Chapter – he is a role MODEL for the “Academia for Society and Industry”, an approach promoted by NM-AIST.

Dr. Askwar Hilonga (1976) posses eleven years experience of working as a researcher, lecturer/senior lecturer, and a project director both in Tanzania and South Korea. At present he works as a Senior Lecturer at The Nelson Mandela African Institution of Science and Technology since Feb 2011. Hilonga contributed to enabling a South Korean company, E&B Nanotech Co. Ltd, to be selected as one of the best promising/emerging technologies empowered to enter the American market in 2011. The selection was done under a program conducted by the Gyeonggi Province (Republic of Korea) in conjunction with the University of Texas, at Austin, after vigorous training conducted both in Korea and in the U.S. When living in Korea, Dr. Askwar Hilonga assisted the leadership of the NM-AIST to establish collaborations with nine Korean institutions. Hilonga comes from a very a poor social-economic background being born in Gongali Village – Karatu, Arusha - Tanzania. After graduating Ph.D in 2010, Hilonga is asking himself an ethical question: “what does my Ph.D mean to my community in Tanzania”? As part of the answer, Hilonga and his wife Ruth Elineema founded a company called Gongali Model Co.Ltd www.gongalimodel.com as a spin-off of NM-AIST for innovative activities to empower and IMPACT people’s lives, according to NM-AIST motto of “Academia for Society and Industry”. Hilonga develops products that solve real life challenges and designs business models that make his innovation affordable even to the neediest in the community. The exemplary invention he just made is the low-cost sustainable water filter (Nanofilter®). Hilonga did his Ph.D (Chemical Engineering) at Hanyang University – South Korea (2010); M.Sc. (Chemistry 2007 and BSc.Ed (Chemistry and Biology) 2004 from the University of Dar es Salaam; and MPH (Master of Public Health), Sahmyook University – South Korea (2012).

GLOBAL EXPOSURE

Dr. Hilonga has a “global-mind” after performing various activities in multi-cultural societies in several countries such as Rwanda (2004), Kenya (2005, 2015, 2016 twice, 2017-2018 many times), Namibia (2005), China (2006), Belgium (2008), South Korea (2007-2012, 2014), Vietnam (2010), Thailand (2011), Ethiopia (2012, 2013), India (2013, 2014), South Africa (2014 Twice; 2016), Norway (2015), United Kingdom (2015, 2016 twice, 2017, 2018, and 2017,2018 - Scotland), Botswana (2016, 2018), France (2016), and Uganda (2017 twice).
He is hard-working (with an exemplary record of meeting deadlines), enthusiastic, passionate, proactive, honest, and trustworthy. He gets along well with his colleagues, and easily makes friends. He is a good team player in various activities, and is a footballer. Hilonga fluently speaks Swahili, English, Iraqw, and Korean. He is married to Ruth Elineema (MBA, Korea) and is blessed with 2 children (Son 10 yrs / Daughter 8 yrs).
