Why I choose Science

Enjoyed biology and really wanted to understand how ‘things’ work at a biochemical level

Science helps us understand how everything worksIf we know how it works, can we improve it, fix problems, anticipate the outcome…

Science make a huge impact on people’s lives, environment and economies - technologies changing all the time

Many and varied job opportunities nationally and internationallyIrish science degree and PhD recognised worldwide

Opportunity to travel – visiting scientist and attending conferences

Teagasc – Dublin Food Chemistry and Technology

The science of meat quality?

• How can science be of interest when all I want is a nice tender, flavoursome juicy piece of meat for my dinner?

Eating quality of meat is variable

• 1 in 5 beef steaks are unacceptably tough

Why is it variable?

What can influence eating quality of meat?

Can we do anything to improve it?

Research Programme

Using molecular biology tool to study gene sequence and expression to gain a greater understanding of economically important traits in agriculture

particularly fertility, health, muscle growth and their response to feeding

Introducing meat quality into Irish beef breeding indices

Has science a role to play in meat products?

Do you like your sausages or burgershard/softjuicy/drysalty/spicyhigh/low fat

Understand how components in meat, ingredients and processing all interact to give you different types of quality

Science-led approach to developing new products

My RoleLead a research group – postdoctoral scientist, PhD students,

undergraduate students Design (new ideas) and manage research projectsHelp guide lab work Help write our research findings into papers for publicationPresent research findings at national and international

conferencesApply for funding to carry out research – SFI, DAFM, EUCommunicate and discuss research ideas with my colleagues

and collaborators Communicate with industry! Focus of research must have

applications focus.

My typical day…A lot of computer work, phone, meetingsManaging projects and people – emails, administrative duties Meet students and colleagues to discuss strategies and resultsWriting grant proposals and papers –reading research papersAttend & present research findings at international conferencesLiaise with colleagues, national and international groups to plan

new projects

On committees, working groups, interview boards, evaluating PhD theses etc.

Scientists…• Love knowledge, • Love exploring, finding out about things• Enjoys working with latest technologies etc• Flexible • Sees the positive in situations• Contributes to developing research area• Energetic enthusiasm• Resilient• Communicates• Self confidence – self belief
