From In Silico to In Vitro to In Vivo
From the moment we step into a classroom, we’re subtly conditioned to see the world in distinct categories. Biology, engineering, public health – each subject occupies its own neatly labeled box, seemingly separate and distinct. We learn about cells and ecosystems in one class, circuits and algorithms in another, and epidemiology and healthcare systems in another. This compartmentalization, while perhaps helpful for organizing curricula, can obscure the deep and intricate connections that weave these disciplines together.
Traditionally, the realms of computational biology and informatics, often referred to as the “in silico” domain, have operated as distinct disciplines from the myriad wet lab fields within the life sciences, which primarily revolve around experimentation using molecular biology tools, cell lines, microbial cultures, and biochemical assays, known as “in vitro” studies. These, in turn, stand apart from fields concentrating on research within animal models and clinical settings, termed “in vivo” investigations. This segregation reflects the diverse methodologies and emphases characteristic of each domain, with computational approaches emphasizing data analysis, modeling, and simulation. At the same time, wet lab experiments delve into biological phenomena through physical experimentation and observation.

The Role of ML in Discovery: Hypothesis Generation vs. Hypothesis Testing
Machine learning has emerged as a powerful tool for generating hypotheses in biological research. By identifying patterns and trends within vast datasets, ML algorithms can predict outcomes and suggest potential avenues for investigation. This predictive capability is precious in complex fields like genomics, proteomics, and drug discovery, where researchers grapple with massive amounts of data. However, biological systems’ inherent variability and complexity often pose challenges for ML models. Even with extensive data, accurately predicting biological phenomena can be complicated due to many biological processes’ multitude of interacting factors and stochastic nature.
Traditional laboratory-based hypothesis testing plays a crucial role. Experimental validation provides a critical reality check, grounding the predictions generated by ML models in empirical evidence. By carefully designing and conducting experiments, researchers can test the validity of ML-generated hypotheses and refine the models based on real-world observations. This iterative process of prediction and validation is essential for ensuring the accuracy and reliability of ML models in biological research.
Ultimately, the synergy between ML and experimental validation drives scientific discovery. The iterative feedback loop, where ML models generate hypotheses and experiments provide validating evidence, allows for continuous refinement and a deeper understanding of complex biological systems. This dynamic interplay between computational prediction and empirical observation holds immense promise for accelerating breakthroughs in fields ranging from disease modeling and drug development to personalized medicine and synthetic biology.
