Introduction

Theoretical and molecular modelling are indispensable in origin-of-life research as they help to predict the behaviour of prebiotic chemicals, the self-organisation of molecules, and the activities of early protocells. The field of origin-of-life modelling has been profoundly impacted by the combination of advances in computational chemistry, systems biology, quantum chemistry, network theory, and AI-powered tools, which have opened a way for the quicker and easier development of models for prebiotic reactions and life’s emergent properties. On the flip side, the challenges in the area still persist: numerous pathways being proposed haven’t been supported by experiments, there are only limited frameworks connecting molecular predictions with planetary chemistry, and most of the abstract models used do not integrate thermodynamic and stochastic realism into their specifications. The following dissertation topics will be dealing with these problems by promoting closer relationships between prebiotic chemistry and biosignature detection, developing Category-Theoretic models further, and putting probabilistic origin-of-life hypotheses to experimental test.

Proposed PhD Title 1: Assessing Origin-of-Life Conditions to Improve Biosignature Reliability in Exoplanetary Science: A Framework for Integrating Prebiotic Chemistry with Life Detection Models

The discovery of life on exoplanets has gradually become dependent on the detection of atmospheric and surface biosignatures. Current models are mainly concerned with habitability and conditions that allow life to exist, while the discussions regarding the origin of life are very limited. According to Keller et al. (2025), this creates a serious problem in exoplanet research: OOL processes, which are never integrated into biosignature interpretation, are still the ones that determine the possibility of life ever coming up. Documents like OWL 2023-2032 and Astro2020 have extensively talked about habitability, yet they have not said a word about the relationship between OOL conditions and possible biosignatures. Thus, it will be difficult to interpret the signals for life unless prebiotic chemistry is linked with the observable features of the planet. It follows that the OOL principles should be integrated if building confidence in biosignature detection is the aim.

Problem Statement:

Currently, the strategies employed to detect life on exoplanets mostly rely on the assumption of habitability and the existence of certain atmospheric biomarkers. However, they do not provide any systematic method to consider the first living matter conditions in the processes of interpreting biosignatures. This neglect can result in the assessments of extraterrestrial life being either unclear or wrong.

Research Gap:

Among the principal decadal surveys (OWL 2023–2032, Astro2020), a quantification of the connection between OOL processes and biosignature interpretation is very rare. The lack of a structured framework for integrating prebiotic chemistry, environmental thresholds, and planetesimal conditions results in a life detection approach that is incomplete and potentially unreliable.

Research question:

How can a systematic incorporation of the origin of life conditions in exoplanet biosignature interpretation frameworks increase the reliability and accuracy of life detection assessments in context?

Outcome:

The first well-structured framework that connects origin-of-life factors to biosignature interpretation and thus, improving the level of scientific certainty regarding future detections by the likes of HWO and LIFE will be a product of this research. Also, it will offer scientists a method for quantifying the context of atmospheric signals, which will consequently lead to a reduction in the misclassification of false positives.

Proposed PhD Title 2. Quantifying the Link Between Origin-of-Life Processes and Exoplanet Biosignatures: Developing Predictive Criteria for False-Positive Discrimination

The new missions, such as Habitable Worlds Observatory (HWO) and LIFE, have the main goal of identifying biosignatures on exoplanets with the highest precision so far. Nevertheless, Keller et al. (2025) state that present-day detection methods do not take into account the origin-of-life (OOL) conditions at all, which may also have a shaping or limiting effect on biosignature production. Presently, the detection models mainly presume that ‘habitat’ equals ‘potential for life’, but the conditions for the start of life to the point of long-term survival can be quite different. Meanwhile, the planetary science documents still refer to OOL concepts, but they have not been incorporated in a significant way into the analysis of exoplanetary biosignatures. Consequently, there is an important void: the relationship between prebiotic chemistry and the detectable atmospheric signals has not been assessed. The importance of this issue is that it would help to distinguish between true biosignatures and abiotic false positives; thus, the reliability of life detection would be improved.

Problem Statement:

Current models fail to distinguish between biological signals and false positives resulting from abiotic chemistry or geophysical processes due to the lack of rigour in quantifying the impact of OOL processes on biosignature strength and detectability.

Research gap:

There is no suitable framework available that enables the establishment of measurable criteria that link OOL pathways, prebiotic geochemistry, and observable atmospheric markers. This situation constitutes a significant gap in life detection methodology and hinders the systematic risk assessment of false positives.

Research Question:

Which measurable signs of life from smaller or larger origins can be traced back to the observable exoplanet biosignature detection to make a better separation between the signals produced by living beings and the false positives caused by non-biological processes?

Outcome:

The dissertation will set forth quantifiable predictive criteria to calculate the reliability of biosignatures and the number of false positives. It will make the scientific basis for the interpretation of life’s signals more robust and will provide a link between the originating potential of planets for life and the detectability of biosignatures that are true through measurement.

Proposed PhD Title 3. Extending Category-Theoretic Models of the Origin of Life: Integrating Stochastic Thermodynamics to Address Idealised Reversibility and Nonequilibrium Dynamics

Recently, Category Theory (CT) has been investigated as a universal mathematical vocabulary for representing the change from prebiotic chemistry to protocells. With its compositionality, it can depict catalytic networks, chemical organisation, and breakthrough functionality, among others. Nevertheless, the CT-based models of the day are built on top of abstractions that are not realistic; the most outstanding among them being reversible interactions and near-equilibrium that do not portray the essentially non-equilibrium, energy-driven character of real prebiotic systems. Dadashkarimi (2024) points out that CT’s abstractness conveys the necessary conceptual clarity but has difficulties in capturing the physical dynamics and stochastic behaviour of primitive chemical systems. This renders the need for a framework that would use CT’s structural strengths together with thermodynamically realistic models.

Problem Statement:

The goal of this dissertation is to improve the current models of Category-Theoretic origin-of-life by adding stochastic thermodynamics principles to the discussion to eliminate idealised assumptions of reversibility and near-equilibrium dynamics. The project plans to develop a physically grounded, compositional framework that will be able to represent realistic prebiotic chemical systems by assimilating energy constraints, irreversibility, and probabilistic state transitions into categorical structures.

Research Gap:

The theories of life origin based on Category Theory currently have a number of limitations, since they are based on idealised assumptions like reversible interactions and near-equilibrium conditions, which actually do not take into consideration the nonequilibrium system, the energy-driven nature of real prebiotic systems. Moreover, the lack of thermodynamic and stochastic elements in CT prevents it from completely describing the physical dynamics of the early chemical networks.

Research Question:

What are the different ways to reformulate Category-Theoretic models of the origin of life to be inclusive of thermodynamic processes that are irreversible, nonequilibrium, and stochastic, and so they give a more accurate picture of the physical behaviour of prebiotic chemical networks?

Outcome:

The doctorate will deliver an increased CT structure that includes the input of stochastic thermodynamics to illustrate irreversibility, the movement of energy, and fluctuations, generating a more physically accurate depiction of prebiotic chemical organisation.

Proposed PhD Title 4. From Molecules to Planetary Signals: Addressing Scope and Idealisation Limits in Category-Theoretic Models of Origin-of-Life Pathways

Category Theory (CT) has become a favoured compositional framework to model the above-mentioned hierarchical transitions, beginning from the primitive life-forms composed of networks of catalytic reactions and ending with rudimentary cell-like structures. The method’s structural purity has opened avenues to unify different stages of the prebiotic process and even suggest the possibility of linking micro-scale chemical evolution to macro-scale biosignatures on exoplanets. Yet, it is the extreme simplifications of the current CT models that Mike Dadashkarimi states (2024/2023) in his paper Towards a Compositional Framework for the Origin of Life, which appeared in Frontiers in Astronomy and Space Sciences. The authors present the argument that these models normally ignore the essential features of the real prebiotic systems, namely thermodynamics and stochasticity, thus limiting their application to the discussion of biosignatures in exoplanetary atmospheres.

Problem Statement:

This dissertation aims to combine the thermodynamic and stochastic aspects with the Category-Theoretic origin-of-life models. This way, it will be possible to have a broader and more realistic view and, consequently, to make more reliable predictions that would connect the atomic origins to the Earth’s planetary biosignatures.

Research gap:

To make the matter of the current state of CT-based models for the molecular origin of life clearer, it can be stated that their idealised assumptions concerning the nature of the system, their focus on very early protocell development, and neglect of the key factors related to kinetics and thermodynamics are the main reasons why they are unable to make any physically realistic predictions. Not only this, but they also consistently struggle to draw connections to the observable biosignatures on planets.

Research Question:

In which way the Category-Theoretic origin-of-life models be converted to accept non-reversible dynamics and higher-order emergent transitions and still deliver the indicators that correspond to exoplanet biosignature detection?

Outcome:

The project will yield a CT framework that makes use of non-reversible and thermodynamically realistic reaction dynamics, connects early-life transitions to detectable planetary signals, and enhances the separation of biological from abiotic sources of biosignatures.

Proposed PhD Title 5. From Probabilistic Models to Empirical Tests: Advancing the Resonance Hypothesis of the Origin of Life

The Resonance Hypothesis, which was put forth by Trincher (2025), offers a mathematically formalised, probabilistic framework for the origin of life that can be understood. The hypothesis assesses the case of early biochemical emergence going on in the ‘resonant’ environment and considers it as the cause of life’s molecule precursors being formed. By way of quantitative plausibility estimates, it is suggested that traditional abiogenesis scenarios might have had a significantly smaller probability compared to the scenarios proposed by the hypothesis, and by orders of magnitude. The hypothesis also combines insights from different fields (physics, chemistry, and philosophy), making it an attractive conceptual framework for early-life studies. Nevertheless, the hypothesis coexists with its rigorous formulation and logical coherence, the geophysical model remains largely hypothetical, dependent on conditional probabilistic justification with no direct experimental verification, consequently, limiting its movement from theoretical plausibility to scientifically confirmed explanation.

Problem Statement:

The main objective of this dissertation is to create experimental frameworks and testable protocols that will allow us to evaluate the empirical correctness of the Resonance Hypothesis origin of life predictions and thus reposition it from being the most statistically persuasive theoretical scenario to being a scientifically accepted model backed by experiment.

Research gap:

Although the Resonance Hypothesis of the origin of life offers a compelling probabilistic alternative to traditional chemical evolution theory, it faces a significant empirical gap. The Resonance Hypothesis, while being a highly appealing probabilistic model, still requires extensive experimental. The hypothesis’s reliance on conditional probabilistic justification and heuristic reasoning creates a difficulty in converting theoretical predictions into empirically verifiable results. Consequently, it is necessary to bridge the gap to confirm the claim of the hypothesis as a scientifically convincing model regarding the emergence of life in ancient times.

Research Question:

What are the methods for empirical testing and validation of the predictions of the Resonance Hypothesis, and what type of experimental evidence is needed to either corroborate or refine its probabilistic models of early-life emergence?

Outcome:

The research will produce A set of experimentally testable predictions derived from the Resonance Hypothesis, Laboratory protocols or observational strategies (e.g., synthesis experiments under resonant stimulation, cymatics studies, spectral correlation analyses), and an assessment of the empirical plausibility of the resonance-based origin-of-life scenario, strengthening its scientific credibility.
