Prem Raj Adhikari
Data Scientist

Hi ! I am a Data Scientist proficient in Big Data and Statistics with a PhD in Machine Learning and Data Mining and 7 years of experience in the analytics sector. Passionate about data analysis and extracting business relevant insights and recommendations from data. I am also a self-motivated team player with an aptitude and desire for continuous learning, professional development and keeping abreast of the latest technologies. Currently, I'm a data scientist at Turku Center for Disease Modeling at Institute of Biomedicine in University of Turku. I am a member of the Endomet Project where the primary focus is on using machine learning and data mining methods in biomarker detection and development diagnostic  tools for different stakeholders such as patients, clinicians and pathologists.

Experience

Data Scientist (February 2015 - Now)

Project Plan: Extract meaning from large-scale heterogeneous data, investigate biomarkers for disease; develop and commercialise disease diagnosis, prognosis, and follow-up software using powerful machine learning and data mining algorithms. The project resulted in disease diagnosis software (webtool) for clinicians, patients, and surgeons, which is currently under trial at a hospital.

Key responsibilities:

  • Optimised and applied state-of-the-art machine learning, data mining, and analysis methods in disease diagnosis

  • Revealing and visualising the structure of heterogeneous data by clustering

  • Identifying and validating biomarkers (Feature Selection) for disease diagnosis. Identified 10 robust markers from tens of thousands of variables. A notification of invention (patent) to the patenting organisations is submitted

  • Predicting the follow-up medical status of the patients (disease, recurrence, infertility, pain). Prediction accuracy improved to over 93% for disease diagnosis, and over 85% for recurrence prediction. Human Accuracy is ~70%

  • Acted as a project manager working closely with different stakeholders such as biologists, clinicians, software developers, business persons, and patients to ensure the project meets the business needs

Machine Learning Researcher (August 2009 - February 2015)

Projects: The project encompassed large-scale machine learning challenges in different application domains; with a focus on learning models from differently represented heterogeneous data collections.

Key responsibilities:

  • Identifying, investigating, and analysing current state-of-the-art statistical data analysis methods
  • Responsible for designing, implementing and evaluating the proposed solutions for data analysis and visualisation
  • Creating, adopting, and implementing new algorithms and methods ensuring high quality research
  • Collaborating with researchers and application area specialists to formulate and document project requirements and plans
  • Creating user requirements and feasibility study documents for the project, finalising the documentation to be published as conference proceedings, journal articles, technical reports, and theses for knowledge dissemination
  • Acting as a central reference and information source, providing assistance for timely completion of the collaborative project

Teaching Assistant (August 2011-February 2012 )

Key responsibilities:

  • Assisting Prof. Erik Aurell in organising the post–graduate course Quantitative Systems Biology
  • Preparing course materials, updating and maintaining course web-page
  • Organising and lecturing the tutorial sessions and reviewing assignments

Research Visit

I visited The Delft Bioinformatics Lab at Delft University of Technology for two weeks from 5th to 17th of December 2011. I worked under the supervision of Assistant Professor Jeroen de Ridder on scale space theory and their application to genes. A longer visit is also planned for again sometime in the future. While in Delft, I gave a talk on my current work and future plans to the group.

I visited Department of Knowledge Technologies at Jožef Stefan Institute for a week from 16th to 20th of September 2013. I worked under the supervision of Professor Nada Lavrač on semantic data mining methods and their application to biological datasets. While in Ljubljana (JSI), I presented my current work and future plans for collaboration to the research group.
