I completed my PhD at University in August 2020, focusing on Benchmarking and Performance Modelling of Data Intensive Applications. My work was suprervised by Prof. Adam Barker.. I am now working at the same university as a Postdoctoral researcher focusing on Adaptive Cloud Brokerage. I am a member of the Systems Research Group
I obtained a BSc. in Computer Science from the University of The Gambia and MSc. in Information Systems and Application (Distinction) from National Tsing Hua University in Taiwan. In 2016, I earned MSc. in Data Science (Distinction) from Lancaster University, UK. In my final project at Lancaster University, I worked with Data Scientist at Christie NHS to help investigate and migrate some of their desperate RDBMS data sources to NoSQL and Big Data Systems. After a rigorous feature comparison and performance benchmarking of various big data systems, we decided to use Hadoop, Spark and MongoDB.

My PhD research focuses on understanding the performance of big data and distributed applications running on cloud computing infrastructure. Our approach uses a combination of benchmarking and predictive modelling to infer the performance of an application running in distributed computing environments. Understanding this behavior can be useful for consumers deploying big data applications in the cloud computing environment.
The problem we are trying to solve is broadly defined as follows: Given a cluster computing environment e.g. Hadoop or Spark Cluster, how can we determine the execution time of an application x or the resource needs of an application x. A demonstration of my latest work is available from Performance Modelling of Data Parallel Applications
So, in basic terms the main objectives of my research can be grouped as follows:

In the School of Computer Science at the University of St Andrews, I am engaged in tutoring and lab demonstration of the following Undergraduate (Sub Honors) courses
I also work with the University of St Andrews ELT foundation program as a tutor. I teach the following modules
There is no free time, but in my free time, I love reading news, reading business and leadership related books. I also watch highlights of football games and I do play sometimes. So if you live around Dundee or St Andrews and want to warm up, please do not hesitate to let me know.
Secondly, I am also very much interested in the politics of my home country. I just can't ignore it!
