Research Centre of the Graduate Institute of Science and Management (GISM), Sri Lanka.
This centre, which is known as “GISM Research Group (GRG)”, was established in 2011 to promote applied research for solving real world problems in health, agriculture, manufacturing, communication and other sectors and industry. GRG has both local and overseas experts from different areas such as Science, Engineering, Applied Mathematics, Information Sciences, Management etc. to work together for solving critical problems in real world using multi-disciplinary approach.
This research centre in backed by GISM which is a higher education institute operates in Sri Lanka since 2010 as an education and research partner to many prestigious Universities and institutions in developed world including Massey University, New Zealand and Edinburgh Napier University, Scotland in the UK. This institute envisages promoting research and consultancy work in this country applying state-of-art technology with the help of experts in reputed overseas Universities.
In Sri Lanka, a large number of technical problems limit improvement of productivity in sectors such as agriculture, industry, health etc. Also there are many health problems such as Diabetics, Kidney diseases, Breast Cancer disease, Heart diseases that require further work for finding appropriate solutions. Problems that require solutions prevail everywhere in the world but many of these cases are specific to Sri Lanka due to identified and unidentified environmental, social and cultural influencing factors. Hence, it is imperative that appropriate research projects are conducted to understand the causes, effect and influencing factors first and then find appropriate solutions to these pressing problems.
I am pleased to inform you that our research forum envisages providing our service to work on some problems in Sri Lanka. Following are some cases we take up seriously to work on:
- Study and understand the exact cause/s of kidney disease prevailing in some areas of the country and find appropriate technical solutions to the health problem that reduces the life span of the people.
- Find most critical influencing factors of diabetes in Sri Lanka and introduce methodologies to reduce the number of patients who suffer from this disease. We also wish to collaborate with experts from both local and western medication systems to find solutions and develop successful treatments.
- As breast cancer is another deadly disease in our country, GRG envisages to developing methods using modern techniques for early detection of breast tumors and find successful treatments.
- Heart disease: As most of the cases relate to health problems in family history, eating habits, stress, alcohol and smoking addiction etc., efficient and accurate investigating systems are required to protect people from this disease. Thus, a proper study is needed to model and analyse data, specific to our people, using mathematical and signal processing techniques.
Apart from these cases, GRG has expertise to undertake research and consultancy work relate to other areas such education and training, engineering and application, meditation and spiritual treatment etc. to help people to upgrade their living standard while supporting the industry to grow for economic development of the country.
The GRG headed by Director–Research will coordinate with public and private organizations to address their problems (technical or otherwise) which affect their production qualitatively and/or quantitatively. GRG maintains a data bank of resource persons to work with GISM on full time or part time basis to support the research projects undertaken by GRG. Based on the type of the problem, a group of research scientists will be appointed by the GRG to work on the problem/issue confronted by the organization and follow up until the expected outcomes are achieved.
Other Research Projects:
In-line monitoring and controlling the withering process in Tea Industry
Withering process is the most important part in black tea manufacture. The removal of moisture in green tea leaves is carried out by blowing hot air through the green tea leaves under a controlled process. This process is required to trigger a series of bio-chemical reactions in tea leaves. The quality of the final product directly depends upon this withering process. The enzymatic changes are ultimately responsible for the production of various bio-chemicals desired for achieving quality parameters in the final outcome. Therefore, there has been a significant demand for developing an appropriate automation system for this important process.
Develop a software and use for the hotel sector
This is an application in a i-pad or similar kept in the table for customers who come to the hotel to take meals or refreshments. They can see the food items available at the hotel and order the items they like. All the information of the items are available in the i-pad including the price, others’ comments etc. The orders will directly go the kitchen.
This software can be developed if any costumer in the hotel sector is interested.
Three-D Image building.
This application is to build a 3-D image of an object using few photo images taken around the object at selected and pre assigned locations vertically and horizontally in certain grid points. The image data will be processed using special algorithms to obtain a meaningful 3-D image.
This outcome can be used in fashion design industry and marketing industry but can be used for generating 3-D image of the objects of interest in general.
Microwave Cancer Detection for Early Stage Diagnosis of a Breast tumor
Measurements using microwave signals can reveal important information about the properties of the scattering media. According to previous experimental results, the properties of normal and malignant tissues, such as permittivity and conductivity, have significant differences, offering great promise as a basis for microwave detection techniques for breast screening. With the help of a suitable inverse algorithm, it may be possible to detect and compute the size and the location of a malignant tumour using in-vivo microwave measurements. We propose a simple and cost-effective technique, and with further developments, this method may be used to detect a tumour before proceeding to other diagnosis processes. In this approach, breast compression is not required because the information about the tumour, if any, can be found using the ratio of the field quantities of the forward and reflected signals measured at the same antenna position. This is the reflection coefficient. The method is safe for breast screening because we use a low power microwave signal and therefore it does not harm the normal breast tissue.

I was at the International Rice Research Institute in the Philippines during 1980, where I conducted research on nitrogen fertilizer losses in rice soils. I was a FAO expert in Soil Fertility and Soil Microbiology attached to the National Soil, Service Laboratory in Ethiopia. I have published around 30 research papers in international journals. These research studies were mainly on organic and inorganic fertilizers, pesticide use, environmental pollution and soil management.
During 2005-2006, as a consultant to the Minister of Agriculture, I was involved in developing the agricultural policy of the Sri Lanka Government. Also, as Chairman, Sugarcane Research Board (2004-2009) I was involved in developing the policies in the sugar sector development of Sri Lanka. I was a consultant to around 20 agricultural development projects carried out in Sri lanka.
I was Director, Advisory Services Dept. of Rubber Research Board (1984-88) and Director – Agricultural Development, Samurdhi Authority (1995-1999) Thus, I have around ten years experience in management/administration of agricultural development projects
