    Evaluating the Computational Overhead and Latency in AI-Based DDoS Detection Systems  Designed, implemented, and evaluated LUCID, a lightweight CNN-based DDoS detection system for computationally constrained environments.  Used Python, TensorFlow/Keras, Kali Linux, multiprocessing, model pruning, quantization, and Optuna-based hyperparameter tuning to develop and optimize the detection system.  Simulated DDoS attacks in virtualized environments and evaluated model performance and computational overhead.  Achieved approximately 90% reduction in training time and 35% improvement in inference speed through model and system-level optimization.  Integrated multithreaded packet capture and real-time prediction with alerting and logging to support practical edge deployment.

    Group 13 Age Detection 1 Facial Age Detection  Developed a CNN-based facial age-group classification system using the UTKFace dataset.  Pre-processed facial images through grayscale conversion, resizing to 150D7150 pixels, reshaping, and pixel normalization.  Built the model using the Keras Functional API, with convolutional, pooling, dense, and dropout layers for 14 age- group classifications.  Applied GridSearchCV and SciKeras to tune model parameters and evaluated performance using accuracy, loss curves, confusion matrices, and classification reports.  Developed a Streamlit application enabling image upload and webcam-based prediction, using OpenCV and the trained Keras model for inference.

STATISTICS RESEARCH PROJECT, Ashesi University

The Impact of Corruption on Governance in Ghana  Analyzed Round 8 Afrobarometer Ghana survey data using R and RStudio, investigating relationships between perceived corruption, democracy, and trust in the police.  Defined research questions, variables, and hypotheses, and structured categorical survey data for statistical analysis.  Created contingency tables and data visualizations to examine relationships among the study variables.  Conducted chi-square tests of independence and post-hoc analysis, interpreting statistical significance and communicating findings.  Evaluated methodological limitations, including the inability of observational data to establish causality, and identified directions for further research.
