I served with Nucleate (Florida Chapter) as the Partnerships Operations Lead, where I organized a statewide AI in Biotech event in collaboration with UF Innovate Accelerate at the University of Florida. At this event and others, I secured industry/academic sponsors and partners who will continue to support and partner with Nucleate Florida Chapter despite my stepping down last month to focus on the final stretch of my PhD. My contributions were also felt in the Grant Writing and Alternative Funding departments, where I trained and handed over responsibilities to the new team. I’m thankful for the opportunities I had to learn, and network while serving with Nucleate. I continue to contribute to the team as an Ex-Leader/Alumnus. Nucleate is TIME's inaugural list of America's Best Incubators and Accelerators in August 2026.

My attention is now focused on completing the final stretch of my PhD, advancing research initiatives at New Life Research Foundation - Neliref Ltd/Gte in partnership with the African Bioinformatics Institute (ABI) based in South Africa, and pursuing our drug discovery programs at Bio-PrecisionAI Health.

I believe some people learn from my journey and benefit from my Eurekas (Eureka means "I have found it”), that’s the essence of sharing it. I felt the need to say this: being visionary and purpose-driven is important, but so is the disciplined pursuit of less. Prioritizing where you invest your energy is essential for deep, focused work. You don’t need to be everywhere, neither do you need everyone’s approval or validation. Focus, strategy, and the right network are what you need.

I’m not involved in everything. I’m focused on succeeding in these areas, building and expanding our partnership base, and making meaningful progress before pivoting to other aspects of my professional and career goals.

In 2024, as part of the National Institutes of Health (NIH) SEED team pitching our technologies in San Diego - California at the BIO International Convention, I scheduled a one-on-one meeting with the NIH SEED Director at the time. She said something that has stuck with me ever since: “Joseph, wherever decision-makers are, there you should be also.”

Being in the startup world, customer discovery is a recurring part of our journey. We interview stakeholders, learn from them, and iterate our technologies to solve real customer needs. Reading ‘Talking to Humans’ at the time further emphasized the importance of engaging stakeholders, including people who may eventually become recommenders, partners, or advocates. Through these customer discovery interviews, we grow, refine our technologies based on feedback, and pivot when necessary.

As we pursue our drug discovery programs at Bio-PrecisionAI Health, Bio-PrecisionAI Health, we have come to understand that customer discovery and continuous engagement with decision-makers are not one-time activities. They are practices we must continue throughout our discovery, development, and pivoting phases.

Graph Engineering over Loop Engineering in Agentic AI

Most builders still design AI agents as a straight line:

Research first.
Write second.
Review third.
Ship last.

Each step waits for the one before it, even when half of them never needed the previous result.

The system does not branch.
It does not parallelize.
It does not know how to recover.

It just keeps feeding one context window until the agent gets slow, confused, or expensive.

The problem is no longer the prompt.

The problem is the shape of the work.

That is what graph engineering fixes.

Instead of forcing every task through one sequential pipeline, you design the agent as a graph:

→ Tasks branch when they can run independently.
→ Multiple agents work in parallel.
→ Results converge when dependencies actually exist.
→ Conditional paths handle different situations.
→ Failed tasks can retry or recover without restarting everything.
→ State and context are separated instead of endlessly accumulating.
→ Human intervention can be introduced exactly where it matters.

The result is not simply a “smarter” agent.

It is a better-engineered system.

AI agents should not just be given better prompts. They need better architectures.

The next generation of agentic systems will be defined less by how long their context window is and more by how intelligently they structure, route, execute, and recover from work.

Stop thinking in chains. Start thinking in graphs.

California bans paraquat, highly toxic herbicide outlawed in more than 70 countries

State is US’s largest user of pesticide that is virtually proven to cause Parkinson’s disease

California is banning paraquat, a highly toxic, controversial herbicide used across millions of acres of American cropland.

Public health advocates characterize it as a deadly substance that is virtually proven to cause Parkinson’s disease. It is already outlawed in more than 70 countries, including China, the UK and the EU. Yet in the US, the Environmental Protection Agency (EPA) reapproved it for use in 2021 and 2024.

California is the US’s largest user of the pesticide, and largest agricultural producer, so advocates have hailed the decision as a major public health win. It is the second US state to prohibit paraquat, following Vermont, and its decision comes after the state legislature passed a 2024 law requiring the pesticide division to re-evaluate the substance’s health risks.

Practical, evidence-aligned guide to lowering oxidative stress and supporting mitochondrial function—especially relevant to neurodegenerative risk like Parkinson’s disease.

1) Nutrition that lowers oxidative stress

Eat a polyphenol-rich, plant-forward pattern

Think Mediterranean-style eating:

Colorful fruits/veg (berries, leafy greens)
Extra-virgin olive oil, nuts, seeds
Legumes, whole grains
Fish (esp. oily fish)

Why it helps: high in antioxidants that neutralize reactive oxygen species (ROS) and upregulate endogenous defenses (e.g., via Nrf2 pathways).

Prioritize specific antioxidant foods

Berries (anthocyanins)
Dark leafy greens (vitamin C, carotenoids)
Tomatoes (lycopene)
Nuts/seeds (vitamin E)
Green tea (catechins)

Ensure key micronutrients for redox balance

Vitamin C & E → direct antioxidant activity
Selenium → supports glutathione peroxidase
Zinc → antioxidant enzyme function

Support glutathione (your main cellular antioxidant)

Sulfur-rich foods: garlic, onions, crucifers (broccoli, kale)
Adequate protein (for cysteine availability)

2) Nutrition that supports mitochondria

Omega-3 fatty acids

Sources: salmon, sardines, mackerel, walnuts, flax
Effects: improve membrane function, reduce neuroinflammation

B-vitamins (mitochondrial coenzymes)

Especially B1, B2, B3, B5, B12
Sources: whole grains, eggs, legumes, meat/fish

Magnesium & iron (balanced)

Magnesium → ATP handling, enzyme function
Iron → oxygen transport (but avoid excess)

Co-factors often studied for mitochondria

Coenzyme Q10 (CoQ10)
Nicotinamide adenine dinucleotide (via precursors like NR/NMN)

(Evidence varies; useful in some contexts, but not a cure-all.)

3) Lifestyle habits with the biggest impact

Regular exercise (most powerful lever)

Aerobic + resistance training
Stimulates mitochondrial biogenesis (via PGC-1α)
Improves insulin sensitivity and reduces ROS over time

If you only pick one intervention: exercise

Sleep (7–9 hours)

Clears metabolic waste from the brain
Reduces oxidative load
Supports mitochondrial repair

Stress management

Chronic stress → elevated cortisol → oxidative damage
Helpful practices: mindfulness, breathing, prayer/meditation, time outdoors

Avoid toxin exposure (critical)

Minimize contact with pesticides (wash produce, consider organic where feasible)
Avoid smoking; limit air pollution exposure when possible

4) Metabolic strategies

Intermittent fasting/time-restricted eating

Enhances autophagy (cellular cleanup)
Supports mitochondrial efficiency

Stable blood sugar

Avoid frequent spikes (high refined sugar intake)
Favor fiber + protein with meals

5) What not to rely on

High-dose “antioxidant megadoses” → can backfire

Single “superfood” fixes → biology is systems-level

Supplements without addressing sleep/exercise/diet

Putting it together (simple daily framework)

Eat: plant-rich, whole foods + omega-3s

Move: 30–60 min/day (mix cardio + strength)

Sleep: protect 7–9 hours

Reduce toxins: especially pesticides/smoke

Stabilize metabolism: avoid sugar spikes, consider time-restricted eating

Bottom line

To reduce oxidative stress and protect mitochondria:

Diet + exercise + sleep do the heavy lifting

Nutrients and supplements can support but not replace these foundations

🌱 Environmental Toxins and Parkinson’s Disease: The Role of Key Pesticides

Growing evidence shows that environmental exposures, especially certain pesticides play a significant role in the development of Parkinson’s disease. Among the most studied are Paraquat, Rotenone, and Maneb. Although they are used for different agricultural purposes, they converge on similar biological pathways that damage neurons.

What these pesticides are used for:

1. Paraquat is a herbicide used to kill weeds by generating toxic oxygen radicals in plant cells.

2. Rotenone is an insecticide (and sometimes used to remove invasive fish) that interferes with cellular respiration.

3. Maneb is a fungicide used to protect crops from fungal infections like blight and mold.

Despite their different targets —plants, insects, and fungi, they share a troubling ability to disrupt human cellular function.

🧠 How they contribute to Parkinson’s disease

Parkinson’s disease is primarily driven by the degeneration of dopamine-producing neurons in the brain. A key hallmark is the accumulation of misfolded alpha-synuclein, which forms toxic aggregates (Lewy bodies).

These pesticides contribute to this process through several interconnected mechanisms:

1. Oxidative stress

Both paraquat and maneb increase the production of reactive oxygen species (ROS)—unstable molecules that damage proteins, lipids, and DNA.

Paraquat is especially potent, undergoing redox cycling to continuously generate ROS.
This oxidative stress promotes Protein Misfolding, including that of alpha-synuclein.

2. Mitochondrial dysfunction

Rotenone directly inhibits mitochondrial complex I, a critical component of cellular energy production.

This leads to reduced ATP (energy) production

Increased oxidative stress

Neuronal vulnerability, especially in dopamine neurons

Notably, rotenone exposure in animal models reproduces many features of Parkinson’s disease.

3. Alpha-synuclein aggregation

All three compounds through oxidative stress and mitochondrial damage promote Protein Aggregation.

Misfolded alpha-synuclein begins to clump together

These aggregates form toxic oligomers and fibrils

Over time, they accumulate into Lewy bodies

This is a central pathological feature of Parkinson’s disease.

4. Synergistic toxicity (especially Maneb + Paraquat)

Studies show that combined exposure (e.g., paraquat + maneb):

Causes greater neurotoxicity than either alone

Accelerates dopamine neuron loss
Increases alpha-synuclein pathology

This suggests real-world agricultural exposure may be more harmful than single-compound studies indicate.

5. Selective vulnerability of dopamine neurons

Dopamine-producing neurons are particularly sensitive because they:

Already operate under high oxidative stress

Have high metabolic demand

Are less equipped to handle mitochondrial dysfunction

This explains why Parkinson’s specifically targets these neurons.

Why this matters

Epidemiological studies consistently link pesticide exposure to increased Parkinson’s risk

Rural populations and agricultural workers are disproportionately affected

These compounds are widely used globally, raising public health concerns

Implications for treatment and research

Understanding these mechanisms points directly to therapeutic strategies:

Prevent alpha-synuclein aggregation

Reduce oxidative stress

Protect or restore mitochondrial function

Bottom line

While genetics plays a role in Parkinson’s disease, environmental factors like paraquat, rotenone, and maneb significantly contribute by:

Damaging mitochondria

Increasing oxidative stress

Driving alpha-synuclein misfolding and aggregation

In short:

These pesticides don’t just kill pests, they can disrupt fundamental biological systems in ways that mirror and accelerate the core pathology of Parkinson’s disease.

“Actually, AI already saves lives.
In several countries, mammograms are examined by AI and radiologists. Reliability is improved.
In the EU, every car sold must be equipped with Automatic Emergency Braking Systems. That's AI. They reduce frontal collisions by 40%.
Modern MRI machines are equipped with AI technology that reduces the time of imaging by 4x or more. You can now get a full-body MRI in 40 minutes for about $1000. Reduced time -> reduced cost -> more/earlier detection.
And that's not counting the progress in medicine enabled by modern AI, including Nobel Prize-winning protein structure prediction.”
