Preparation Guide for the Junior Research Scientist Position at Global Public Health Research Foundation (GPHRF)
1. Understand the Role and the Organization
• Study the mission of GPHRF – improving population health through evidence‑based research, partnerships, policy dissemination, and capacity building.
• Review the job description line by line and note how your education, research experience, and technical skills match each responsibility.
• Familiarize yourself with public‑health topics mentioned (maternal‑child health, epidemiology, environmental health, food safety, health economics, universal health coverage) so you can discuss relevance during the interview.
2. Align Your Academic Background
• Ensure your degree (BSc or MSc in Computer Science & Engineering or a closely related field) is clearly highlighted in your CV.
• List any coursework or projects that involved health‑related data, statistics, or biomedical informatics.
• If you have a thesis or final project that used ML/DL on health data, prepare a concise summary (objective, methods, results, impact).
3. Showcase Research and Publication Experience
• Compile a list of all conference papers, journal articles, or thesis‑based publications. Include full citation, your contribution, and a link or DOI.
• If you have pre‑prints or technical reports, mention them as well.
• Prepare a one‑page “research highlights” document that can be attached to the application form.
4. Strengthen Technical Credentials
a. Python Programming
– Review Python 3 best practices: modular code, docstrings, type hints, and PEP‑8 compliance.
– Practice writing clean scripts for data loading, preprocessing, model training, and evaluation.
b. Version Control and Linux
– Refresh Git commands: clone, branch, commit, merge, rebase, pull request workflow.
– Work comfortably in a terminal: navigation, file manipulation, using editors such as vim or nano.
c. Machine Learning & Deep Learning
– Re‑run a classification project using scikit‑learn: data split, cross‑validation, hyperparameter tuning.
– Build a small neural network in PyTorch (or TensorFlow/Keras): define layers, loss function, optimizer, training loop.
– Document the process with comments and a README file.
d. Computer Vision Basics
– Load an image dataset with torchvision, apply transforms (resize, normalization, augmentations), and train a simple CNN for image classification.
e. Natural Language Processing Basics
– Take a text corpus, clean it (remove HTML tags, punctuation), tokenize, and create embeddings using pretrained models (e.g., GloVe, FastText, or BERT).
– Train a text classifier (sentiment, topic) using scikit‑learn or a lightweight transformer model.
f. Multimodal Vision‑Text Experience (optional but advantageous)
– Experiment with a project that concatenates image features from a CNN with text embeddings from a transformer, then feeds the combined vector into a classifier.
g. Data Handling Skills
– Practice merging multiple CSV files with pandas, handling missing values, and performing feature engineering (scaling, encoding categorical variables).
– Use NumPy for numerical operations and ensure you can convert between pandas DataFrames and NumPy arrays.
– Load and preprocess images using PIL or OpenCV; practice resizing, cropping, and converting to tensors.
5. Build a Portfolio of Relevant Projects
• Create a public GitHub repository for each project listed above. Include a clear README, requirements.txt/conda environment file, and sample data or links to open datasets.
• Highlight at least one project that directly relates to public health (e.g., disease prediction from demographic data, analyzing health‑related social media text, imaging for pathology).
6. Prepare Application Documents
a. CV / Resume
– Use a clean, professional layout.
– Sections: Personal Details, Education, Research Experience, Publications, Technical Skills, Projects, Languages, Professional Memberships (if any).
– Keep the length to two pages maximum.
b. Cover Letter
– Address the letter to the HR team at GPHRF.
– State the position you are applying for and where you found the announcement.
– Summarize why you are a strong fit: education, research experience, relevant ML/DL projects, and motivation to work in global public health.
– Mention your ability to work in a collaborative, interdisciplinary environment and your commitment to GPHRF’s mission.
c. Supporting Documents
– Upload PDFs of your academic transcripts (highlighting relevant courses).
– Attach copies of published papers or provide DOI links.
– Include the GitHub repository URLs for your key projects.
d. Application Form
– Fill out every required field accurately.
– Double‑check spelling of names, email address, and phone number.
– Upload the documents in the order requested by the form.
7. Prepare for the Selection Process
a. Anticipate Technical Questions
– Explain the difference between supervised and unsupervised learning.
– Describe the steps you take to prevent data leakage.
– Discuss how you would handle class imbalance in a health‑outcome dataset.
– Be ready to write a small code snippet (e.g., pandas data cleaning, PyTorch training loop) on a whiteboard or screen share.
b. Anticipate Research‑Oriented Questions
– How would you design a study to evaluate the impact of a nutrition intervention using machine learning?
– What ethical considerations arise when working with health data, and how would you address them?
– Describe a time you collaborated with non‑technical stakeholders (e.g., public‑health professionals) and how you communicated results.
c. Prepare Questions for the Interviewers
– Inquire about current research projects that involve multimodal data.
– Ask about the typical workflow between data scientists and public‑health experts at GPHRF.
– Clarify expectations for the first three months (probation period) and key performance indicators.
8. Logistical Preparation
• Verify that you have a stable internet connection and a quiet environment for virtual interviews (if applicable).
• Ensure your webcam and microphone work correctly; test with a friend beforehand.
• Keep a copy of your CV, cover letter, and project portfolio open on your computer for quick reference.
9. Follow‑Up After Application
– After submitting the form (deadline: 5 December 2025), send a brief acknowledgment email to hr@gphrf.org confirming receipt of your application.
– Mark 15 December 2025 on your calendar as the date by which you will know if you have been shortlisted.
– If you do not hear back by that date, you may assume you were not shortlisted; do not request further status updates.
10. Professional Conduct
– Remember that GPHRF is a smoke‑free, fee‑free recruitment environment.
– Do not pay any money or provide personal banking details during the hiring process.
– Maintain confidentiality of any proprietary data or research you may encounter during the interview stage.
By following these steps you will present a strong, well‑aligned candidacy for the Junior Research Scientist role and increase your chances of being shortlisted and ultimately offered the position. Good luck!
