this story starts 13 years ago I was a graduate student in the neurobiology

graduate student in the neurobiology

graduate student in the neurobiology department here at UCSD and I went into

department here at UCSD and I went into

department here at UCSD and I went into Student Health one day because I hadn’t

Student Health one day because I hadn’t

Student Health one day because I hadn’t been feeling well and at the end of that

been feeling well and at the end of that

been feeling well and at the end of that day I went home with the diagnosis of

day I went home with the diagnosis of

day I went home with the diagnosis of advanced testicular cancer now normally

advanced testicular cancer now normally

advanced testicular cancer now normally this is a terrible thing but in this

this is a terrible thing but in this

this is a terrible thing but in this case it set me on a path that has

case it set me on a path that has

case it set me on a path that has brought me here today so during the

brought me here today so during the

brought me here today so during the course of my treatment and Memorial

course of my treatment and Memorial

course of my treatment and Memorial sloan-kettering I realized something

sloan-kettering I realized something

sloan-kettering I realized something pretty profound most of the medications

pretty profound most of the medications

pretty profound most of the medications that I was taking or derived from nature

that I was taking or derived from nature

that I was taking or derived from nature now I’m a scientist and have been a

now I’m a scientist and have been a

now I’m a scientist and have been a biologist my whole life and I didn’t

biologist my whole life and I didn’t

biologist my whole life and I didn’t know this so I was blown away and I

know this so I was blown away and I

know this so I was blown away and I decided that when I got back to San

decided that when I got back to San

decided that when I got back to San Diego I would change the course of my

Diego I would change the course of my

Diego I would change the course of my studies and learn how to do this so when

studies and learn how to do this so when

studies and learn how to do this so when I got back the administration was very

I got back the administration was very

I got back the administration was very generous and let me change the focus of

generous and let me change the focus of

generous and let me change the focus of my dissertation so I embarked on this

my dissertation so I embarked on this

my dissertation so I embarked on this journey and found an incredible

journey and found an incredible

journey and found an incredible community here at UCSD that was doing

community here at UCSD that was doing

community here at UCSD that was doing this work in a very cutting-edge fashion

this work in a very cutting-edge fashion

this work in a very cutting-edge fashion one of the first things I learned is

one of the first things I learned is

one of the first things I learned is that over 65% of all our drugs are

that over 65% of all our drugs are

that over 65% of all our drugs are actually derived from nature from

actually derived from nature from

actually derived from nature from morphine which is derived from the poppy

morphine which is derived from the poppy

morphine which is derived from the poppy plant and changed the course of surgery

studies began to emerge regarding the human microbiome all of these drugs are

human microbiome all of these drugs are

human microbiome all of these drugs are produced by microbes so these studies

produced by microbes so these studies

produced by microbes so these studies powered by the advances in genetic

powered by the advances in genetic

powered by the advances in genetic sequencing and in computational power

sequencing and in computational power

sequencing and in computational power actually began to show something amazing

actually began to show something amazing

actually began to show something amazing the human microbiome is much bigger than

the human microbiome is much bigger than

the human microbiome is much bigger than we ever expected it’s actually

we ever expected it’s actually

we ever expected it’s actually outnumbers in cells the human cells by

outnumbers in cells the human cells by

outnumbers in cells the human cells by ten to one genetic composition is

ten to one genetic composition is

ten to one genetic composition is actually a hundred to one versus human

actually a hundred to one versus human

actually a hundred to one versus human so we are not necessarily humans it’s

so we are not necessarily humans it’s

so we are not necessarily humans it’s changing the way that we think about

actually doing another way to think

actually doing another way to think about synthetic versus natural

about synthetic versus natural

about synthetic versus natural naturally-occurring chemistry is to plot

naturally-occurring chemistry is to plot

naturally-occurring chemistry is to plot it in space this is what synthetic

chemistry much more broadly so I left graduate school with these ideas and I

graduate school with these ideas and I

graduate school with these ideas and I was hoping that I would be able to

was hoping that I would be able to

was hoping that I would be able to somehow harness this chemical language

somehow harness this chemical language

somehow harness this chemical language this chemical diversity to more

this chemical diversity to more

this chemical diversity to more efficiently yield new breakthrough

efficiently yield new breakthrough

efficiently yield new breakthrough therapeutics and with the hypothesis

therapeutics and with the hypothesis

therapeutics and with the hypothesis that if we started with a tremendous

that if we started with a tremendous

that if we started with a tremendous chemical library this chemical diversity

chemical library this chemical diversity

chemical library this chemical diversity this language and we tested it

this language and we tested it

this language and we tested it repeatedly across different diseases

repeatedly across different diseases

repeatedly across different diseases over and over again it would yield a

over and over again it would yield a

over and over again it would yield a tremendous dataset and if you use this

tremendous dataset and if you use this

tremendous dataset and if you use this data set and combine it with the modern

data set and combine it with the modern

data set and combine it with the modern computational power AI machine learning

computational power AI machine learning

computational power AI machine learning deep data mining we would be able to

deep data mining we would be able to

deep data mining we would be able to yield better new therapeutics like ever

yield better new therapeutics like ever

yield better new therapeutics like ever before so over the last five years with

before so over the last five years with

before so over the last five years with an incredible team of young scientists

an incredible team of young scientists

an incredible team of young scientists and entrepreneurs we’ve launched this

and entrepreneurs we’ve launched this

and entrepreneurs we’ve launched this effort and actually validated this

effort and actually validated this

effort and actually validated this approach starting with the ocean

approach starting with the ocean

approach starting with the ocean we’ve been all over the world collecting

we’ve been all over the world collecting

we’ve been all over the world collecting amazing samples this is us in Curacao

amazing samples this is us in Curacao

amazing samples this is us in Curacao with Fabien Cousteau we talked our way

with Fabien Cousteau we talked our way

with Fabien Cousteau we talked our way onto the sub and we brought up these

onto the sub and we brought up these

onto the sub and we brought up these sponges which are now part of a

sponges which are now part of a

sponges which are now part of a medicinal chemistry collection we go

medicinal chemistry collection we go

medicinal chemistry collection we go back to our sample of chemical space

back to our sample of chemical space

back to our sample of chemical space what we’re doing is actually expanding

what we’re doing is actually expanding

what we’re doing is actually expanding it right we’re making it bigger we’re

it right we’re making it bigger we’re

it right we’re making it bigger we’re expanding the possibilities for drugs

expanding the possibilities for drugs

expanding the possibilities for drugs and so one of the approaches that we use

and so one of the approaches that we use

and so one of the approaches that we use to start mining it is something

to start mining it is something

to start mining it is something developed here at UCSD called molecular

developed here at UCSD called molecular

developed here at UCSD called molecular networking so molecular networking

networking so molecular networking

networking so molecular networking allows you to see the similarities

allows you to see the similarities

allows you to see the similarities between all of these dots each of these

between all of these dots each of these

between all of these dots each of these dots represents a molecule and instead

dots represents a molecule and instead

dots represents a molecule and instead of finding a needle in a haystack it’s

of finding a needle in a haystack it’s

of finding a needle in a haystack it’s really treating each dot as a needle or

really treating each dot as a needle or

really treating each dot as a needle or perhaps a key that has a lock and so

perhaps a key that has a lock and so

perhaps a key that has a lock and so this approach actually allows us to see

this approach actually allows us to see

this approach actually allows us to see the similarities between these keys and

the similarities between these keys and

the similarities between these keys and the possibility that they’ll work on

the possibility that they’ll work on

the possibility that they’ll work on several locks or on which locks they

several locks or on which locks they

several locks or on which locks they might work and then as we overlay

might work and then as we overlay

might work and then as we overlay disease results as we test in parasitic

disease results as we test in parasitic

disease results as we test in parasitic cancer

cancer

cancer immune immunity we can begin to ask

immune immunity we can begin to ask

immune immunity we can begin to ask which of these dots is actually useful

which of these dots is actually useful

which of these dots is actually useful for let’s say rapidly dividing cancer

for let’s say rapidly dividing cancer

for let’s say rapidly dividing cancer cells and this is the first place that

cells and this is the first place that

cells and this is the first place that we pointed this approach and the first

we pointed this approach and the first

we pointed this approach and the first molecule that came out is actually

molecule that came out is actually

molecule that came out is actually currently part of a targeted cancer

currently part of a targeted cancer

currently part of a targeted cancer therapeutic that’s about to enter

therapeutic that’s about to enter clinical trials

clinical trials

clinical trials hopefully the most recent area that

hopefully the most recent area that

hopefully the most recent area that we’ve been pointing this is immune

we’ve been pointing this is immune

we’ve been pointing this is immune modulation can we find something that

modulation can we find something that

modulation can we find something that actually modulates the human immune

actually modulates the human immune

actually modulates the human immune system to treat cancer better or to

system to treat cancer better or to

system to treat cancer better or to treat infection or to prevent autoimmune

treat infection or to prevent autoimmune

treat infection or to prevent autoimmune disease but really my favorite story is

disease but really my favorite story is

disease but really my favorite story is about malaria this is work that we’ve

about malaria this is work that we’ve

about malaria this is work that we’ve done with the Bill and Melinda Gates

done with the Bill and Melinda Gates

done with the Bill and Melinda Gates Foundation over the last two years now

Foundation over the last two years now

Foundation over the last two years now malaria is something we don’t think

malaria is something we don’t think

malaria is something we don’t think about a lot here but it affects over 200

about a lot here but it affects over 200

about a lot here but it affects over 200 million people each year with the

million people each year with the

million people each year with the majority of them in sub-saharan Africa

majority of them in sub-saharan Africa

majority of them in sub-saharan Africa and it kills a thousand children a day

and it kills a thousand children a day

and it kills a thousand children a day so we started digging into our big nest

so we started digging into our big nest

so we started digging into our big nest of opportunity and quickly found

of opportunity and quickly found

of opportunity and quickly found something in less than four months that

something in less than four months that

something in less than four months that actually treats malaria perhaps in a

actually treats malaria perhaps in a

actually treats malaria perhaps in a totally new way incredibly potent and is

totally new way incredibly potent and is

totally new way incredibly potent and is currently being evaluated further here

currently being evaluated further here at UCSD so the reason that this is my

at UCSD so the reason that this is my

at UCSD so the reason that this is my favorite story is that if you think

favorite story is that if you think

favorite story is that if you think about where we collected this organism

about where we collected this organism

about where we collected this organism it was the Atacama Desert

it was the Atacama Desert

it was the Atacama Desert we found this algae growing the Atacama

we found this algae growing the Atacama

we found this algae growing the Atacama Desert brought it back processed that

Desert brought it back processed that

Desert brought it back processed that tested it and found this thing that was

tested it and found this thing that was

tested it and found this thing that was present and less less concentration than

present and less less concentration than

present and less less concentration than uranium is found in salt water so it was

uranium is found in salt water so it was

uranium is found in salt water so it was tiny abundance this was remarkable but

tiny abundance this was remarkable but

tiny abundance this was remarkable but when we looked in our data we found it

when we looked in our data we found it

when we looked in our data we found it in 25 different hosts from across the

in 25 different hosts from across the

in 25 different hosts from across the planet just this tiny tiny presence of

this incredibly potent anti-parasitic

this incredibly potent anti-parasitic agent from all over the world so as we

think about our planet we think about

think about our planet we think about diversity
